Floating point and string template parameters?  Awesome!  And Happy 
Thanksgiving!

By the way... how did you get around the symbol length issue for 
template string parameters?  Is a checksum part of the name or some such?

I didn't. It's necessary to be conservative in how long a string you use.

No.

Truly awesome! I'm itching to have to a play with these. Sounds like I 
can have a 90% hack reduction in my metaprogramming code!

BTW, in the changelog, the link to std.demangle doesn't work, and I 
couldn't find it on the phobos page, either.

"Added std.windows.charset (thanks to Stewart Gordon, D/28246)."

Excellent!  Only, I think you mean 28264 or 28426, not 28246.

And you mistyped my name in the comment to fromMBSz.

More observations while I'm at it:

- The comment in std.file states that the toMBSz there is deprecated, 
but you haven't given it the deprecated attribute.

- toUTF8(wchar*) is nowhere to be seen.  OK, so it's a fairly trivial 
wrapper, but still....

Stewart.

Sorry about that. I'll fix it.

A question: When are the implicit template properties supposed to apply? 
There's a interesting corner case involving properties of built-in types.

With the code

template q()
{
    const char [] q = "abc";
}

const int a = q!().length;

does not compile. Fair enough, it's looking for q!().length, not 
q!().q.length.

Although potentially the rule for evaluating a!().b could be: look for 
a!().b, if not found, look for a!().a.b
I don't think this recurses, even if a!().a was a template.

So, I tried
const int a = (q!()).length;
This doesn't compile either. Based on the error message, it seems that 
parentheses suppress the implicit property feature. Is this behaviour 
intentional? (Maybe it could be useful).

Anyway,

const int a = (q!() ~ "").length

works as expected, as does:

template strlen(char [] str)
{
    const int strlen = str.length;
}

const int a = strlen!(q!());

I tried this with 0.140:

template q()
{
    const char [] q = "abc";
}

const int a = q!().length;

void main()
{
    printf("a = %d\n", a);
}

and got:
    a = 3
as the output.

Sorry, I got that a bit wrong. Here's a minimal test case:

--------------
template cat(int n)
{
   const int dog = n;
}

const char [] q = "qqqq";

const int thisfails = cat!(q.length).dog;
--------------
bug.d(9): no property 'length' for type 'char[]'
----------------

But if you replace the last line with:

const int a = q.length;
const int thisworks = cat!(a).dog;

it works. So it seems to be a simple order-of-evaluation bug that 
doesn't have anything to do with implicit template properties. I'll post 
it to d.D.bugs.
