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?
Thanks,
Ludo’.
