I am not convinced yet. I think it is something that
std.concurrency is doing (perhaps because it relies on
Variant?). Otherwise there is no problem with what derelict
does. The following code compiles:
maybe you are right about Variant, and yet it still not compiler
bug, but phobos bug. rewriting std.variant and std.concurrency
just because of forward refs is no go.
i think problem is that with a struct we can't just generate code
for this methods(toHash,opCmp,etc) by comparing its address, even
if it's not extern(C/C++) and not found by linker, or do we
actually could?
