Why is "call expr" a more enticing syntax than "yield *expr" ?

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. -- Greg
