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.
