Guix,

I just encountered the following:

foo.scm:4:2: error: url-fetch: unbound variable
hint: Did you forget `(use-modules (guix build download))'?

Actually importing that module, instead of (guix download), will
cause some other very hard-to-debug error that I can't remember
but coincidentally helped someone fix on #guix the other day.

Now I understand how they got to that bad place.

Kind regards,

T G-R

Oh, bad hint indeed.

Now, the program cannot determine that of the two ‘url-fetch’, only one
makes sense.

Should it search further and propose all the possible options? In
general there won’t be more than a couple of options.

Thanks,
Ludo’.
