It's a good idea, but unfortunately we don't have partial

When I think of it, it might be better to let the compiler detect
it and do this as a general optimization. Because you might be
able to collapse two consecutive among() into a single lookup if
the code-structure allows for it. So an early library
optimization could reduce the ability to optimize at a later
stage… *shrug*
