    Right, seems to be worth fixing.

While the R5RS does say this, that I regard this as a nice extension of
Guile that I really like.

It allows you to do things like

    (apply equal? list-with-objects) ,

which, in my opinion, are nice.  Otherwise, we would be have to deal
with having to iterate on the lists everywhere.

I think introducing this change would break a lot of code.  At least
it would break a lot of my code (and, from his implementation of
and-map and or-map, I guess Neil Jerram's).

Hmm.
