I would spell this dict.zip(keys, values). It brings to mind the current
implementation, but allows for optimisation. It's also slightly less
parenthesis heavy, which I think makes it a little more readable.

I think this is one of those cases where the gain is small enough that
writing the helper function is often not worth it, but big enough that
people would use it if it already existed. That might be a small window,
but it's there.
