Don't worry, there wouldn't be any change in
semantics. What I'm talking about would only
be done when executing a "yield every" statement,
and it would only be an optimisation -- the
"yield every" statement would still have the
same semantics as a for-loop with a "yield"
in it.

I was originally thinking of using "yield from",
in the interests of re-using an existing keyword.
But since it can be a pseudo-keyword, that's
not really an issue.
