No, static ctor/dtor is not a trivial mechanism. There is a runtime graph
analysis to make sure there are no cycles, and then run them in the proper
I think this feature has to be disabled.
I meant that we could get something mostly working using init sections, but
it's probably not a good idea.

Yes, this also depends on moduleinfo, like static ctor/dtor.
Same with this, not worth the hack.

This requires vtables and typeinfo. I've seen virtual functions
implemented in C (back when I wrote Xt widgets). I also think that with
D's compile-time power, one could probably recreate it using templates.
I don't want to recreate it, I want to avoid it.
The issue I have with allowing classes is the implications of classes. D
classes are infinite-lifetime, meaning requiring GC. What we would end up
with is classes written for the minimal no-gc version of D, and classes
that were written to be allocated on the GC heap in full-D. And both would
be named 'class'
This is a very good point. extern(C++) classes do not depend on druntime,
and currently do not have their destructors run by the GC!
