I like this direction --- and like everyone, I wish for a better name.

I don't like `submodule' or `sub' for this, because it's a particular
way of creating submodules, not a general form for submodules.

How about `facet', with the terminology that "facets" are implemented
as "submodules"?

For example, a module with a `main' facet could be

  #lang racket/base


  (facet main
    (require racket/cmdline)
    (command-line .....))

but you could also use `(facet main ....)' multiple times to add parts
to the `main' submodule.

I agree with Eli that if we have a good replacement for `submodule**',
then we may not need this one. For example, I like

 (facet test ....)

better than

 (when-testing ....)
