Why is "call expr" a more enticing syntax than "yield *expr" ? On Thu, Feb 5, 2009 at 9:31 PM, Greg Ewing <greg.ewing@canterbury.ac.nz> wrote:

What's so special about your proposal that requires a new keyword?
I was thinking about the proposals that are made from time to time for things like
yield *foo
to yield all the items from a sub-generator. I was also thinking about what could be done to make using generators as coroutines more convenient, and I came up with the idea of a new statement
call expr
which would be equivalent to
for x in expr: yield x
This happens to be the same as what "yield *" would do, so it kind of unifies the two issues.
