The applicative-numbers package [1] provides an include file. With ghci,
the include file isn't being found, though with cabal+ghc it is found.

I'd sure appreciate it if someone could take a look at the

That did it. I've added :set -package applicative-numbers to my .ghci and
am back in business. Thanks!
IIUC, there's an inconsistency in ghci's treatment of modules vs include

Thanks for the clarification, Duncan. Seems an easy partial solution would
be a single pass (before CPP) that notices just the #include directives.
Consult the package database to find those packages. That route would find
direct includes but not indirect ones. An optional and still-easy next
