Python Programming Language :: `yield` in a `try/finally` block, pre-Python 2.5


	`yield` in a `try/finally` block, pre-Python 2.5 I'm trying to emulate the Python 2.5 behaviour (PEP 342) of generator functions where the `yield` statement is in a `try/finally` block. Basically, where the `finally` block is guaranteed to run even if the generator doesn't finish running: it simply runs when the generator is garbage-collected. Does anyone know a good way of doing this? I'm looking to see if there's a way to bring about an exception in another frame in pure Python, but I haven't found anything yet. I had the same problem, you can see: http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/130004 for a solution.

I thought of doing something like that, but in my program, it's important that the order follow the actual nesting order. That is, I have a few nested generator each of which has its own 'finally', and I need the innermost ones to run first. How can I deal with that?
