`map()` expects a function as first argument that will be applied to the
elements in the other the arguments which have to be iterable. That you
can give `None` as a function and the resulting behavior is IMHO a very
ugly thing and has not much to to with the semantics expected from a
`map()` function. The `None` is not the default fill value but a
placeholder for the identity function.
