Which leaves us with no basic datastructure that can hold both
positional and named arguments. This is a problem because in a call,
they can be combined.
An array could hold both, but with only one small and minor
inconvenience: pairs are either all positional, or all named. I
sincerely believe that this is a feature, not a problem, because arrays
are singledimensional, and having pairs mean two different things on the
same level is, as this new proposal also indicates, confusing at best.
