I seem to recall hearing that the primary reason it hadn't been
implemented is because of Python's super-dynamism (to make up a
word).  That a function could be a tail recursion in one call, but
the calling the same name could then become rebound.  I'm making up
the example, but I think it was something like this:

  def kablooie(*args):
    if not args:
      def kablooie(*args):
        woah()
    do_something(args)
    kablooie(args[1:])

where tail recursion optimization would do weird things.
