Note that we aren't talking about comments. We're talking about 
ddoc strings. They just have very similar appearance to comments, 
but they are distinct entities defined by D to be part of the AST 
(and the compiler will parse their contents too if you ask it 
to!), unlike regular comments which are discarded before parsing.

That's really the big difference that puts me over the top: 
documentation strings in D are defined to be attached to the 
symbol by the compiler. They're ALREADY different than plain 
comment-comments, just the compiler withholds this information 
from the code.
