Right, yield_if_true is a regular function, that's the whole point.

There'd still only be one kind of generator, defined by the presence
of the yield keyword. Nothing would break.

The function that calls yield_if_true (or some other function up the
call chain) would need to be a generator, if necessary made such using
the traditional workaround
    if 0: yield
