My convention is that anything that evaluates to either #t or #f has a
'?' at the end.  Thus both predicates and flag variables are named
like this.  Using 'is-' or something like that is just how languages
that don't allow punctuation in symbols workaround the limitation.
Ruby is particularly annoying because while a method name can have a
question mark at the end, a variable name cannot.

tl;dr - Good idea!
