`export source x from "y"`

[lucacasonato]

Should we also add this as a shorthand for:

import source x from "y";
export { x };

[guybedford]

export { a } from 'b' will not create a local a binding, instead it is only the external binding name.

Similarly, perhaps an export source x from 'y' would do the same thing by default - that is, it is not a shorthand but a new syntax entirely.

We could in theory decide either way though.

Note that we still don't have export foo from "foo" syntax: https://github.com/tc39/proposal-export-default-from

[ljharb]

oh true, in that case that proposal would add export source foo from 'foo' as part of adding export foo from 'foo'.

that underscores, though, the need for that proposal, since export source { default } from 'foo' wouldn't be available as a workaround otherwise.

[lucacasonato]

We decided during the Module Harmony call to defer this until export foo from "foo" is a thing to not create asymmetry.

Something for a follow up proposal (or included in the default export proposal).
