Subject: Clearing TOPLEVEL_BINDING for reuse

Is there anyway to delete all the local and instance variables in a
Binding?

I've been working on a test framework and ideally I'd like the tests
to run at the toplevel rather than within the scope of some class. But
to do this I need to clear out the variables between each test script.
