    Having actually used LISP systems with "edit and continue", it's a good
thing that Python doesn't have it.  It encourages a "patch" mentality, and
the resulting code is usually disappointing.

    What the original poster seems to need is a global analysis
tool that insures that all names used are defined.  Like "pylint".
