Re: [Configobj-develop] check function for list of list of integers

Hi Faheem,

Not sure to what you are trying to convert these values but eval
is not what you want I believe. Also note that
using eval like this makes your app vulnerable to code injection
because you don't sanitize the string you hand over.

Here is your problem: You hand an object of type "list" to a function that
doesn't arguments of that kind.
eval's docstring sais:

    eval(source[, globals[, locals]]) -> value
    
    Evaluate the source in the context of globals and locals.
    The source may be a string representing a Python expression
    or a code object as returned by compile().
    The globals must be a dictionary and locals can be any mapping,
    defaulting to the current globals and locals.
    If only globals is given, locals defaults to it.

I think one option would be to quote your values in the config,
so you'd explicitly get a string and not a stringlist.
I'm not so firm with the configobj internals but it seems that
it is interpreting this stringlist before alling your test.
HTH,
