eh the question is what is "most"? Even my little 200 line thing 
has: functions, templates, scope closures, structs including 
operator overloading, static arrays, slices, pointers, 
__traits+ctfe, scope guards, switches, and more.

I just now added basic classes and that wasn't too hard 
(copy/pasted some code from the real druntime for the typeinfo 
and so on).

But it doesn't do AAs, throwing exceptions, dynamic arrays and 
other nice features. Looking at druntime's src, exceptions look 
hard, and while dynamic arrays, heap closures, and others can 
easily 'work', they will leak memory, so I don't think they will 
ever be really good without gc. Exceptions are doable though from 
what I can tell.


Anyway I think this is enough to do some real programs and feel 
kinda nice. Surely no worse than C at least.

Yeah, the typeinfos are a pain in the butt, even trying to 
copy/paste it from druntime isn't that easy. I'm sure this would 
strike again if we actually tried writing a real program.
