Tcl is a glue language that encourages you to glue external processes
together.  This is much less emphasized in Python, so I doubt that it
will be as useful.  I don't think it's worth the maintenance
nightmare.  Copying the Tcl code doesn't mean we have no maintenance
-- the Tcl code undoubtedly uses lots of Tcl runtime convenience
routines, which we would have to adapt to the Python runtime

That's why we have sys._getframe(). ;-)
