does anyone have a ruby module that emulates C enums, so that if you
want a bunch of uniquely-enumerated constants you can just say something
like:

enum( :FOO => 1, :BAR, :BAZ, :BUZ )

...? I thought I saw something like this awhile ago, but maybe I was
mistaken...  it should be trivial to implement; but I didn't want to
code it if someone else already had.
