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.
