Re: [Python-Dev] Add an ExecutionLoader abc to importlib or to runpy?

2009/7/15 Nick Coghlan :

While runpy is the only client in the standard library for the get_filename() method, the method is still a PEP 302 extension. I documented the extension in the PEP as loaders are the only things reliably in a position to provide the filename details that runpy needs to set __file__ and sys.argv[0] correctly and until importlib came along PEP 302 itself was the only real documentation of that API.

Yes, sorry about that :-)

Since importlib is now the "go-to" location for people that want to write their own PEP 302 importers and loaders, I would say that it is also the right place for the new ExecutionLoader ABC.

Agreed. (But I said that before...) Paul.
