With great trepidation, I have to say that there is a way to pull this off. You could check out PadWalker. From the description:

PadWalker is a module which allows you to inspect (and even change!) lexical variables in any subroutine which called you. It will only show those variable which are in-scope at the point of the call.

This software appears to be brand new, so use it with care. What I want to know, however, is how you can justify a need for something like this. Yes, I've read the rest of the thread about how you don't need to worry about malicious code because it's being supplied by programmers in your company (what if they write really awful code? what if one of them is quitting and has a nice time bomb in the code?), but I still wonder what problem you are really trying to solve. For the vast majority of programmers, when the apparent solution is terribly convoluted and requires "tricks" to pull off, this suggests that you should rethink the problem. In other words, if you back up a step and let us know what you're trying to do, maybe we can offer safer alternatives.
