Is it?  :-)

My impression is that one would always write:

  (with-imported-modules … #~(…))

or possibly combining multiple expressions:

  (define e1 (with-imported-modules … #~(…)))
  (define e2 (with-imported-modules … #~(… #$e1 …)))

in which case modules are appended.

I couldn’t think of a use case where one would literally write:

  (with-imported-modules …
    (with-imported-modules …

Perhaps I’m missing some pattern where it could be useful though?
