[mod_python] using compile_code objects

I am thinking of writing a validation code in the definition of a
field that I receive from a web form. For example, if I have a field
named 'state', I would define a dictionary like this:

_states = ['AZ', 'AL', 'MO']
_state = {'name': '',
          'max-length': 2,
	  'validator': 'in n in _states return true'
then when I read my req.form['state'] I can say something like

if eval(_state['validator']) == true:

I am wondering a coupling things:

1) has anyone else done something like this?
2) what kind of performance penalty is there for compile and eval
3) other issues unique to modpython that would make this undesireable
4) how to parameterize a python string that I would compile (so I
could pass in req.form['state'] to the _state['validator'] function.

Hopefully this makes sense.
