it's practically a ".di" file, but in compact binary representation. or 
even a full ".d" file for that matter. it's already parsed, checked, 
analyzed, maybe even some code emited -- but no AST/type information is 
lost. well, .dcus doesn't keep AST, but D ".dcm" can. ;-)

they also can be used by tools too.

i think that this is the area that can be left to "platform-specific" 
part of the specs. maybe even omited completely, as it's highly backend/
arch dependent. if someone want to squeeze every cycle possible, he knows 
that his code will be unportable mess. ;-)
