And just a quick suggestion: can we standardize what imp.sourcetopath() and friend are supposed to return if the interpreter doesn't support bytecode? I will probably have to rely on that for something so it would be best to say now whether it should be None or raise an exception so there is no divergence on this between VMs.

Returning None sounds like the most straightforward option. "cached = None" will just mean "for whatever reason, we have no cached filename for this file". It may be the cached file doesn't exist, or the interpreter simply wasn't in a position to figure it out in a user visible way.

Cheers, Nick.
