I know, it's cool, I even blogged about it!
(https://mbork.pl/2021-03-27_The_interactive_clause_and_modes).

But what I'm asking is something very different.  I explicitly don't
want commands related to a certain mode (major or minor), but commands
defined in a specific file.  I know that every function somehow "knows"
where its source is (because it's shown by `describe-function'), but I
want to be able to get that info (for ex., in a function I'd put in
`read-extended-command-predicate', which I knew about, since it's
mentioned in that blog post, but I forgot, so thanks for that!).

Best,
