Thanks for this little piece of information! Great stuff. You 
wrote

"When building an UFCS chain (in the style of component 
programming), you will often run into situations where a certain 
operation is not UFCS-able. There are multiple obvious ways to 
prepend the string, but neither are very satisfactory"

And this has happened to me many times. The solution "Break the 
UFCS chain and use a local temporary variable" makes me angry, 
because by having to do so all the beauty of chaining is lost.

A very slow (i guess) workaround could be:

"test".toUpper.only.map!(a => "This is a " ~ a).front.writeln;

vs the new one:

"test".toUpper.Identity!(a => "This is a " ~ a).writeln;

Shouldn't be slow, your just giving the optimiser some work to

Trying on d.godbolt.com it seems a lot of extra-code is generated 
for the first version.

Anyway I think I'm going to rename it "apply". :)

"test".toUpper.apply!(a => "This is a " ~ a).writeln;

It sounds better.

The d.godbolt.org compilers seem a little out of date. I have 
found problems with their codegen/optimisation that doesn't 
happen in more recent versions.

ldc 0.15.2 based on llvm 3.5.1 reduces both chains to identical 
asm.

DMD and GDC don't generate compatible outputs, so it's not that
straightforward to have both together. ;-)

d.godbolt.org is better than asm.dlang.org because GDC emits assembly,
you have more information to play around with (and syntax highlighting
works thanks to .file and .loc assembler directives).

asm.dlang.org is a basterdised version that removes all features
because DMD emits object code, and there is no useful information you
can pull from objdump.

It is nice that you can test the latest daily on asm.dlang.org though...

Iain.

Very nice. There is also a similar package protected template in 
std.typetuple, `Alias`. I used it a lot but last applicability 
case with UFCS chain didn't come to my mind. It looks very 
elegant.

I had plans to introduce it as a public helper in std.meta under 
the name `Symbol`, would that make sense?

Yeah, because the sound in `you` or the letter <u> is not a full 
vowel but a semi-vowel /j/ (cf. German `ja`), also: a "voiced 
palatal approximant":

https://en.wikipedia.org/wiki/Palatal_approximant

Whenever a phonetic /u(:)/ becomes a /ju(:)/ (for whatever 
reason), rules for vowels no longer apply, simply because it is 
(phonetically speaking) no longer vowel, e.g. an + V => a + /j/. 
Cf

a utilitarian point of view (*an utilitarian) /juː/

The spelling rule upsets you, because there is a mismatch between 
what you see on the page and how you pronounce it (vowel vs. 
consonant/semi-vowel). It also works the other way around:

- an STL expert
- a PhD student

<s> describes a consonant but is pronounced with a vowel here 
/es/. Thus, you have to write `an`.

Just follow your natural way of speaking and you'll be fine. Read 
it out to yourself. And let's be honest, it sounds really crap 
when you read "an UFCS", bahhh!

Yes, well, the problem is that "an U" sounds completely fine in 
my head!

The way you pronounce the U letter in the English alphabet is the 
same (not sure if identical) as the Russian letter Ю, which is 
considered a vowel in Russian.

In that case you'll just have to learn the rule: if it's a single 
letter, it has to be `an`. Sorry, I didn't realize that /j/ is 
treated as a vowel in Russian. I was thinking of languages I'm 
familiar with, and there /j/ is always treated as a consonant. Is 
the Russian sound a fricative or a pure vowel without any 
friction (= obstruction)?

 The way you pronounce the U letter in the English alphabet is 
 the same (not sure if identical) as the Russian letter Ю, 
 which is considered a vowel in Russian.

 In that case you'll just have to learn the rule: if it's a 
 single letter, it has to be `an`. Sorry, I didn't realize that 
 /j/ is treated as a vowel in Russian. I was thinking of 
 languages I'm familiar with, and there /j/ is always treated as 
 a consonant. Is the Russian sound a fricative or a pure vowel 
 without any friction (= obstruction)?

Can't answer that question, but <Ю> is actually [ju] in 
isolation, that is, a glide + a vowel. When preceded by a 
consonant, that glide is not pronounced, instead the consonant 
gets palatalized. Thus it would be better to say that /ju/ is 
treated as a vowel, not /j/.

 Read it out to yourself. And let's be honest, it sounds

 Yes, well, the problem is that "an U" sounds completely fine 
 in my head!

Hm, a glide is not necessarily a fricative. In English the /j/ 
sometimes comes close to /ç/, as in German `ich`. A glide would 
be more like /ɪu/, however, in this environment glides tend to 
have some sort of friction, it's almost unavoidable. Interesting, 
though, how the same sounds are perceived differently in 
different languages.

A truly polymorphic identity function in D would be more involved:

template id(a...) if (a.length == 1)
{
     static if (__traits(compiles, { alias id = a[0]; } ))
         alias id = a[0];
     else
         enum id = a[0];
}

static assert(is(id!int == int));
static assert(id!1 == 1);

Also, an 'isEqual' template would be needed to unify 'isSame', 
'is' and '=='.

Actually I do find more specialized names/implementations useful 
in this case. For example, just the fact that you use 
`unaryFun!(a => a)` instead of `Identity!(a => a)` makes code 
more readable and intention clear even if effect is the same.

Thanks for good article

little mistake: return from void function:

/// Search a website for something, and parse the
/// first search result's webpage.
void getItemInfo(string itemName)
{
     // Let's go! First, construct the URL.
     return ("http://www.example.com/search?q=" ~ 
encodeComponent(itemName))
      .......

Fixed, thanks. Though, you technically still can use "return 
expression" in a void function, as long as expression's type is 
void :)
