delegates with C linkage

No problem, I'm glad that we have reached an agreement.

It would be great, if the DMC will provide such extensions like the dthiscall (for
member functions) and the dcall (for static functions). Additionally would be
great if DMC will works on other OS than MSWindows. But probably there are only my
dreams ;)

Btw.
I think there is a good chance for create the set examples which show how to use D
features on the C level. I will thinking about it in my free time :) The idea is
really interesting and it would be useful(especially to better understand these
mechanisms) for some people.

The delegates are called by exactly same way as any other member function. Put ptr
= 'this'(context pointer) to EAX and call funcptr (pointer to function). If I
remember well, the 'this' pointer is passed to functions by ECX in C++. The
delegate structure layout is described in ABI. ABI, disassembler and
trail-end-error method will give you (and me too, because I still need to explore
many things) an answer to many questions.

Thanks for confirming my suspicions.
