c should have been a property of globalThis, but wasn't. It's as though there is a {...} scope in the way, but I can't see how that would be.

This is a side effect of using eval() to evaluate the code. pmEval would be better, but we can't use that due to issue #84

@caleb-distributive let's revisit now that https://github.com/Distributive-Network/PythonMonkey/issues/84 is solved
