You're welcome. I hadn't done it before because I couldn't figure out a reasonable way of implementing it.

I don't know if you are talking about DMD being in a public repo, the contract inheritance or both. But anyway, I'm glad you could finally do both =)

Thanks Walter.

;)

Now, thanks to the public svn we can track changes easily. This will help development of gdc too!

Btw today Michael merged dmd 1.035 and i'm close to finish dmd 2.015

See you.

I'm glad you guys have picked up gdc.

There are some tricky bits to doing contract inheritance, I hope gdc and ldc don't have trouble with it.

You guys are doing awesome job with GDC, thank you _VERY MUCH_!

GDC is the only D2 compiler for 64bit architecture...

Actually, there are no D2 compilers for 64 bit. GDC's support for D2 is very minimal, I don't know how it compares to LDC's, but I'd guess they were about the same (GDC might be slightly further ahead actually, I've never tried it). Either way, DMD is pretty much the only choice for a D2 compiler currently.

What tricky bits are those?

It's outlined in the code comments, but it's implemented by making the contract code a nested function. The overriding function calls those nested functions of the overridden function(s). In order for this to work successfully, the 'this' pointer and the stack parameters must wind up in the same relative position on the stack.

I'm still none the wiser about why it absolutely has to be done like this instead of the simpler solution I proposed years ago.  But in any case, thank you for finally getting round to it!
