I wasn't really considering the repeated genearation on `io` in the `while` example...so now I see a clear benefit to the syntax. I guess I would say I am now lukewarm about adding this additional operator. It makes at least one logical structure nicer...but I wouldn't have been heartbroken if it wasn't accepted though.
