These suggestions sound fine to me, although I don't have a strong
opinion either way.  I'm happy to leave these details to others to
decide.

Actually, for better or worse, Guile's '@@' form does not require the
named module to be imported using 'use-modules', so I don't think this
benefit strictly exists as stated above.  However, I agree that it's
good practice to list all imported modules in the '#:use-module' clauses
at the top of the file wherever possible [*], and that there may be some
benefit in declaring the use of 'computed-origins' at the top of each
file.

      Thanks,
        Mark

[*] It's not always possible in the presence of cyclic module dependencies.
