Also, currently yield looks very similar to return and I think this
is a nice thing as it is similar semantically. yield($foo) would
give it different semantics, imho.I love this point a lot. Return is very common and yield is some
kind of return.
I agree also: yield behaves far more like a return statement than a
function call. (In a sense, a yield is a return that doesn't discard the
current function's execution state.)
Which (as it happens) reminds me of the difference between
return $foo;
and
return ($foo);
