Yes, it seems the site hasn't been updated yet. And not just that page, 
the URL referenced in http://d.puremagic.com/issues/show_bug.cgi?id=960 
(listed as fixed) doesn't seem to be updated either.

They're provided in the zip though (dmd/html/d/function.html and

The website version of future.html looks fixed to me. That's why I marked it as
"fixed". Is your browser using a cached version of that page?

Aren't labeled breaks and continues basically glorified gotos? Or is the

Win32.  We're still investigating, but building the same code with DMD 
1.0 gives us a HelloWorld EXE of 90,652 bytes.  With 1.005 the same code 
gives us a HelloWorld EXE of 113,180 bytes.  I have yet to try 1.006 but 
reports indicate that the size is roughly the same as 1.005.  I think no 
one simply noticed this until 1.006 experimentation began today.  If I 
had to hazard a guess, I'd say most of the size change is probably a 
result of the TypeInfo changes post-1.0, but it will take a while to dig 
through object files to sort all this out.

with 1006, the result is 114,716. That's 26% larger than 1.0 ?

Turns out we have been using different flags.  My numbers above are with 
"-release -O -inline" set.  Without these flags the 1.0 EXE is 92,188 
bytes.  This will be a more useful comparison vs. Kris' number above.

That's likely due to the typeinfo's necessary to implement the type

With 1007, this dropped by a half-kb to 114,204. Possibly due to a 
little code motion.

Now that typeinfo et al are isolated in separate segments, how do we get 
the linker to drop all the unused ones?

I ask, since the example used for tracking down the lib issues has the 
following characteristics:

code ~120kb
data ~60kb

Looking at what's represented by data, a rough guess is that an 
elimination of unused data would reduce it by perhaps as much as 75%

Best D release ever!

But the way you are numbering DMD versions is really annoying :-(

"1.006" does not express how much changed. The last software I saw that
used decimal versions was Netscape Navigator, and before that I can't
even remember. Most software companies I know deprecated this scheme of
version numbering for a good reason.

3 or 4-piece version numbers are largely used today, and they express a
lot better the life history of a software.

1.000 should have been called 1.0.0;

From 1.001 to 1.004, they should have been numbered 1.0.1 until 1.0.4;

Now, 1.005 and 1.006, both introduced sensible changes to the language
spec, so 1.1.0 and 1.2.0 for them.

This also allows one to refer to things like "version 1.1 of D spec".
Today, we have to say "the D spec as it was between 1.005 and 1.006"...

Also, version numbers are not decimal numbers. 1.10 is greater than 1.9.
No need for leading zeros.

This seems a sensible change. Version.Major.Minor is very common and 
very intuitive. Version for code incompatible changes, Major for new 
additions to the spec, minor for bug fixes. You can keep your current 
numbering scheme for minor ticks. Thus 1.0.001, 1.0.002, etc. As Miles 
suggests, you could even retroactively bump the new "major" version to 
reflect the new features (mixins and compile time functions).

I'm impressed. Last releases are the best I've ever seen.

As i understand function at compile time are interpreted (by some kind of VM)?

Now, when i think about it, and about modular design of D (and compiler),
I think it wasn't so hard to implement. Any way, great job!

How times have changed. When I started paying attention to D (Aug 2005), 
the website and spec had a defensive feel ("not as powerful as C++, but 
much  simpler"). And there was a link to the very first D announcement, 
which had a list of "Features to drop from C++", which included "templates".

Yes, it is pretty amazing how powerful D was at 1.0 compared to Walter's 
earlier ideas.

 From 2001/08/14:
"I know that templates likely will be a big issue. I intend to address 
it in version 2 of the language. The way C++ does it is simply too 
complicated for me, I am trying to find a simpler way, so much more 
thought needs to be expended there."

* Codeview for classes now gives correct LF_CLASS

i'd say that this issue is only partially solved in 1.006.
type strings for classes now get the correct LF_CLASS, but symbols of
those types are still marked as pointers to structs. hence they cannot
have the LF_CLASS leafs associated with them, but use the (obsolete?)
struct leafs (marked as forward refs) that exist for each class leaf.

example:

module mymodule;
class class1 { ... }
// ...
class1 myclass = new class1;
// ...

will generate two CV type strings:

class 0x1004 'mymodule.class1' field list: 0x1001 properties: 0x0
struct 0x100b 'class1' field list: 0x0 properties: 0x80

the symbol "myclass" will be marked as a pointer to struct 0x100b.
besides the (probably obsolete) indirection, i think there is no clean
way to tell that 0x100b and pointer-to-0x1004 describe the same type.
