I'm looking into giving memory back to the OS as well.  It will take 
some re-engineering of the GC, but it seems quite doable.

Yup. There are a few bugs I'd like to see fixed to.

BTW, Why isn't this getting fixed? people known how to fix this, several 
solutions have been thrown out there. this should have been fixed a long 
time ago.

here's my take on it:

If the symbol is over 1Kb*, MD5 it or something and use that. Hash them down 
to 128bits and your chances of collision are so remote it's not even worth 
thinking about.  If you need to be able to go back to the original, stuff 
a table in the .obj that maps the two. This wouldn't make for human readable 
link errors but the gzipping that is used now doesn't either. 

* or pick your size

     * a way to detect ref in a delegate parameter list


Huh. After writing this, in a sudden flash of insight, I reinvented a method
that has been in use in std.bind for ages now (props to h3).

Consider the following code:

 template _isRef(C, size_t which) {
   alias ParameterTypeTuple!(C) pt;
   pt[0..which] pre;
   const pt[which] test;
   pt[which+1..$] post;
   const bool r=!is(typeof(C(pre, test, post)));
 }
 template isRef(C, size_t which) { const bool isRef=_isRef!(C, which).r; }



What does this mean?
Succinctly put, if (and only if) a parameter is ref, then trying to call
the delegate/function type in question with a constant value for that parameter
will fail. The const bool r expression literally means "true if calling C with
a constant test fails to produce a return value".

Should there be a place to collect metaprogramming thingies like this so people
don't have to reinvent the wheel?

 I vote std.meta! :)

hehe... Tango had a meta package until CTFE came along and rendered the 
bulk of it pointless.  This particular routine would make sense in 
std.traits though.

Right, my mistake. Sorry. (same to Sean)

In other, not entirely unrelated, news, scrapple.tools' /fix/ now preserves
refness of its arguments :)
(not that anybody uses that except me (sadly), but it will make my code a bit
easier)

If I could add something to the "small things" wishlist:
A pragma to tell the compiler to inline all occurences of a function and not
generate its body in the object file separately. It could unclutter generated
code from numerous useless proxy or otherwise simple functions that don't do
much, but get generated in flocks for example in template expansion. Could also
be used to prevent functions meant solely for CTFE from ending up in the binary.

Yeah, really, "inline" should be a function attribute, never a file attribute,
and it should be used.  That said, I too am pretty tired of major compiler
changes.

At the moment, Walnut cannot compile with DMD 1.21 or later because of some bug
or unmentioned feature implemented in that version.  It has something to do with

struct Value {
  union {
   struct {}
   int i;
   bool b;
   char[] c;
  bla bla.
}

and later doing something with b.  I'd be able to say more, but the error
message is 100% ambiguous and doesn't mention a file or line number.

The exact string I get looks like:

C:\Code\walnut>make
dmd bla bla bla
Error: 'b' is not a member of 'Value'

--- errorlevel 1

I worked on reducing the error to a small example, and I filed a related bug:
http://d.puremagic.com/issues/show_bug.cgi?id=1738

In the process of reducing the error, I guess I lost some of the context for the
error, but I think it seems to be related to the assignment of FALSE in
structure.d:
#   FALSE = { b:false, type:TYPE.BOOLEAN, access:ACCESS.READ },


Note that I'm not defending that DMD rejects your code. My bug report only gives
an example of an error message that should include a line number. I hope this
helps, but it looks like the compiler is malfunctioning in a couple of ways when
it tries to process your code. I only identified one of the malfunctions (lack
of
a line number).


By the way, to come up with the reduced example, I basically used the method
described at:
http://www.prowiki.org/wiki4d/wiki.cgi?D__Tutorial/BugReports


 The exact string I get looks like:
 C:\Code\walnut>make
 dmd bla bla bla
