mod_speling for python

[PT]

Hi,
  I'm not looking to get into a debate about case-sensitive vs.
insensitive programming languages,
but I was looking for suggestions about how it might be possible to
add a hook to the python parser similar to the Apache mod_speling
module (links below).  So that for example if there is a NameError
exception, python walks the globals() and locals() to see if it might
be just a minor spelling/capitalization error.

I can see how this might be done for ImportErrors, using ihooks or iu,
but I don't see how to do it for NameErrors. The python compiler
module doesn't seem to be the answer.

I know there are drawbacks, disadvantages, this is "evil", etc.  I
only wanted to know what ways there are to add such a hook if it is
possible without altering the C source for python itself.

Possible End-User Solution A:
  Simply add an "import spelling" to a python file to enable
spell-checking, sort of like how you use the psyco module (speaking of
which, how many times have you misspelled that).

Possible End-User Solution B:
  Create an alternative executable that wraps the python interpreter. 
This wrapper may or may not have to use its own source code parser,
like the unreleased mobius-python project.
