Yes, it may be that all the operators that return integers or booleans have no side-effects, but that seems like something we should not rely on. I'm tempted to suggest that we add !land and !lor instead, which would take only bit arguments. But that isn't very C++-ish.

I'll leave the final decision to someone with a stronger opinion on the matter.
