Everyone keeps giving regular expressions which include provision for the
characters before the '_'. No need. This will do nicely:
m/_$/ ...or just /_$/
Means: "Match a string that has '_' as the last character". You don't need to
explicitly deal with the preceeding characters if there is no '^' anchor at the
beginning and you don't need to match them if you are not capturing them.
