So we should make sure that we don't bite ourselves with any
primitive <-> object boxing when interfacing nicely with guava...
It should be fine, but there are places where it will not (e.g. passing
a Function to a Vector.apply() would, if allowed,
probably result in a lot of ephemeral object crea

properties:
f(x, 0) = x for any x
f(0, y) = 0 for any y
