[Jprogramming] wat? (seems like a spurious value error from f.)

[Raul Miller]

I am not comfortable with this line of thought, which has to do with paths
and searching other locales. All the names are in the writenif locale and I
am referencing a verb in that locale for its fully qualified name. So, for
the purpose of resolving names in its definition, the current locale should
be the writenif locale.

See also slides 17, 19, 25 and 26 of the Locales lab.

So I feel like something else has to be the issue here.

Thanks,
