You argue for a two-level system of non-lexical names to support
configuration - okay. But why does that imply you have to drop
the lexical naming altogether, instead of using a three-level system
(from external to internal to lexical names)?

Also, in a two-level system of external and lexical names, could one
not model the coordination level by a registry/configuration module?

// using loose syntax
module registry {
module jquery = <external remote or local path>
export jquery
}

module client {
import {jquery: $} from registry
}
