Arrays are a kind of Collection.  Smalltalk's collection classes have a
very rich protocol.  If you start with Collection in a Hierarchical
Browser, you'll see a dozen classes that derive from Collection and are
optimized for different things.

The key methods are #select:, #detect:, #reject:, #collect:, and
#inject:into:.  Learn those first, because your methods would be
built trivially with them, and then could be placed at Collection, not
at Array, since your problem is more general than Arrays. :)
