Actually, about the names of function value'd variables that we want to
use or suggest for advising.

Indeed. Maybe a lot or most of the cases of function value'd
variables are predicate valued variables.
BTW, there is a case that is not so sexy: the case of variables that can
be bound to a function but also allow other values (like nil, t, a
string). We also have these cases in our sources. One must not install
advises for these.
