I'd like to hear the answer :) .
Have to stay at the purists side on this one. I like bool to be bool cause I'm
that kind of guy that can't tolerate inconsistence (however I do tolerate it
cause don't have much of a choice right now) and I'm putting all my hope in D.
However both (the purist and the pragmatic) ways could coexist in the same
language I guess.
