It's customary not to prefix predicates by `is_'.
For instance, it's `empty?', not `is_empty?'; `frozen?',
not `is_frozen?'; `finite?', not `is_finite?', etc.

   foo.a? Foo

On the other hand, that doesn't read very well. :-)

Actually, I guess you could argue that the no-`is_' convention
doesn't apply for parameterized methods.
