Some other interesting examples.

--- Ruby
obj.is_a? Class       # Considers all ancestor classes
obj.instanceof? Class # Only considers immediate class
obj.class == Class    # Same as above, naturally

--- PHP
is_a(obj, 'Class')


The terms 'is' and 'is a' seem to be everywhere.

(But I'm actually perfectly fine with the cast() style.)
