I've written a PEP about this topic. It's PEP 340: Anonymous Block
Statements (http://python.org/peps/pep-0340.html).
Some observations:
1. It looks to me like a bare return or a return with an EXPR3 that
happens
to evaluate to None inside a block simply exits the block, rather
than exiting a surrounding function. Did I miss something, or is
this a bug?
No, the return sets a flag and raises StopIteration which should make the
iterator also raise StopIteration at which point the real return happens.
Only if exc is not None
The only return in the pseudocode is inside "if exc is not None".
Is there another return that's not shown? ;)
I agree that we leave the block, but it doesn't look like we
leave the surrounding scope.
