Hmm. The existing cross-references there feel a bit ad-hoc to me already,
and the proposed additions even more so. Surely we don't want to conclude
that every function that takes or returns an array needs to be cited on
the functions-array page; and that idea would be even sillier if applied
to strings. How can we define a less spur-of-the-moment approach to
deciding what to list?
The patch as shown might be just fine, but I'd like to have some rationale
for which things we're listing or not listing.
