I have no problem with this specific change, but this method of solving
problems is going to turn D into a horrible language with all kinds of
weird edge cases. I left Python for D mostly because the language was
becoming one hack built on top of another; it would be nice if D could
avoid that path. The occasional kludge may be necessary, but it shouldn't
be normal or the first thought.
