I changed the method names to enum_constants and enum_bit_constants.

I wasn't sure what you meant by this.  I tried changing the
above to be 'class Enum", and then have the method names
be "Enum.constants" and "Enum.bit_constants", but that didn't
seem to work.  I checked Pickaxe 2, RAA, and RubyForge for
an Enum module, but didn't come up with anything.  Then again,
this is the first time I tried searching RAA or RubyForge for some
module, so I'm probably doing it wrong...
