This PEP is to change the if _name_ == "_main_": ... idiom to if _name_ == sys.main: ... so that you at least have a chance to execute module in a package that use relative imports.

Ran this PEP past python-ideas. Stopped the discussion there when too many new ideas were being proposed. =) I have listed all of them in the Rejected Ideas section, although if overwhelming support for one comes forward the PEP can shift to one of them.

I'm -1 on this and on any other proposed twiddlings of the main machinery. The only use case seems to be running scripts that happen to be living inside a module's directory, which I've always seen as an antipattern. To make me change my mind you'd have to convince me that it isn't.
