I played around with it.

1. It works. It's amazing. I guess it's a bit like Rosetta for 
Linux.

2. It's slow (about 8x). Probably don't try to build LLVM inside 
it.

3. There seems to be some problem with creating processes using 
std.process. Everything just segfaults. This prevents D tools 
like Dub from doing pretty much anything.
