Has anyone figured out how to bind D to C++ on any include/importable level?
(source, AST, OBJ files, extern'ing to the *.h files)

If they have, maybe we can set up a project to automatically bind C++ projects
in, and Walter might add it to his linker?

For example, matching scrambled names by scrambling  a copy of the D ones,
matching it, binding it?

Or perhaps if Walter allowed extern(C++) by matching the identifiers in the
AST's and passed the extern(C++) segment to the digital mars C++ compiler with
the shared identifiers?

Just my thoughts...

There already is a project to automatically bind C++ to D, it's just not 
particularly complete or accurate.

http://www.dsource.org/projects/bcd/

The method is simple: Generate a C binding to the C++, then generate a D 
binding to the C.

PS: extern(C++) is a terrible idea. It wouldn't be cross-compatible.

Great link.
It was as a result of writing this...

...that I switched to D. It seems that even the compiler writers don't 
know this stuff (several emailed me about it). C++ portability is a 
complete fiasco.

Also, like Walter, you look nothing like I imagined :P.

I agree with all above, great article :P.

Ironically I found that article when trying to learn how to use pointers to
member functions and it helped me learn how to use them adequately. :D

That's a 9 year old document last updated 6 years ago.  C++ has come a

Ah, yes - didn't notice that. I just saw "Last modified January 22,
2007" on the bottom of the page. But wait.. they have actually updated
it after 2001. I'm not sure how true that is anymore, but it's still
interesting to see a page like this.

Just as C compilers are not always ABI-compatible.  It's
just that ABIs for C are more standard than for C++.
There have been, for example, good quality C compilers
that used name mangling to achieve type-safe linkage.

 Yeah, even this (http://www.mozilla.org/hacking/portable-cpp.html) tells

I cry; most of what it says doesn't apply to compilers
from about the last decade.  This is what happens when
languages are hugely successful (in terms of installed
base) -- they gain legacy burdens.

If D does things well, you don't need to spread FUD
about other languages.  By all means compare, but
naive bashing of other languages doesn't make the D
community look healthy.
