Yeah, is-expression syntax is one of the dark, ugly corners of D that unfortunately we're stuck with, because changing it now will totally break a LOT of code for merely cosmetic reasons. I honestly wish that one day this mess could be cleared up, though I'm not holding my breath for it. T -- "Computer Science is no more about computers than astronomy is about telescopes." -- E.W.
