Quite useful would also be
meth.source_location => [String, Fixnum, Fixnum] # to designate which
character it started at, to make it easier to go in and extract the
original code.

Or even meth.source_location => [[begin char], [end char]] that would
be nice [though not necessary, I suppose, since once you have the
beginning, you can scan for the end].
This would enable meth.to_s more readily.
Thanks!
