let me get this straight? is the original question how to strip a string
and remove quotes?

  /^("?)(.*)\1$/.match(self)[2].strip

this only does double quotes and its striping after the quotes removal.
is that what's wanted? well, i'll assume so. what about without regexp?

  return str[1..-1].strip if str[0..0] + str[-1..-1] == '""'

hmmm... you'd think there'd be a real simple way to do this without
regexp, can it get any simpler?
