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.
