There's been nothing stopping people from commenting dmd's source 
in the past, but it barely has any.

I guess anything to encourage more would be good. Though I think 
it is VERY important to comment on the why in implementation.

Knowing what things do is nice, and we could use some comments 
(especially on the module level!), but that basically makes sense 
once you get into it and there's a wiki article to help you get 
started.

The why can be extremely hard to figure out looking at the code 
alone though.
