That's what I meant by importing all the exports.
I'd prefer it if the syntax for that was

import M from "wherever";

That way I could think of import is doing something like destructuring
where the other syntax below is just getting some of the exports.

import {foo, bar} from "wherever"';

I completely agree. Plus if this is taken away then the "import" keyword
can be used to get the whole module as in my example above. At that point
maybe there is no need for the "module" keyword.
