This is not another option, it's just a variant on Jonathan Fine's "key
object" idea with a new name.

This is contradictory, and not possible in Python without a lot of work,
if at all. You want `named("k", 3)` to evaluate to 3, but 3 has no `.name`
attribute. So you can only have one: either `named("k", 3)` evaluates to
a special key object with a .name attribute "k", or it evaluates to 3.
Pick one.
