I'm trying to set up an if clause to exit if an answer given is anything but
either any case combination of 'y' or 'yes'. This is what I have:

exit if $ans =~ m/[^y|^yes]/i;

The brackets are a group, square brackets are a character class. It is
probably a good idea to ignore whitespace around the error as well.
