FWIW (and I know this is minor quibbling) I prefer the present
indicative -- "the list returned by listofvars contains ..." or
something like that.
Slightly less minor -- it would be good to look at the code and see
exactly what is the test used to determined what's a constant. For
example, maybe listofvars calls constantp (that would make sense but
there's no guarantees). Then we would say "any variables for which
constantp is true" or something.
