Yes.  That works if I change the 'it' to 't'.  Looks like the
'collect' method is equivalent to Python's 'map' function.  This
statement is still not as simple as I would like, but it definitely
beats the equivalent Python.

This is the first example I've seen where the difference between Ruby
and Python is more than just personal preference.  Thanks.
