OK.  I guess the simplest approach to editable strings is to have a new type of array
that has multiple segments and implements the buffer interface.  Then the re module
can be extended to handle the buffer interface, if it doesn't handle it already.
Doesn't sound too bad--if I get industrious I might hack this up.
