It does not look too simple either. Whereas I can easily
build valid Python identifiers which are extremely unlikely
to clash with any identifier I can have in my program, it
seems impossible to get an identifier which cannot be
shadowed later . What about renaming
name-> _name_, call -> _call_, func-> _func_, defarg->_defarg_ and
checking that the argument list
does not contain such reserved names by means of an assert statement?
