G'day all.

Quoting Janis Voigtlaender <[EMAIL PROTECTED]>:

I agree.  Indeed, if you look at the source code, the quantifications
_are_ generated, they're just not printed.  The reason is that the
output was (re-)designed for use on IRC where space is at a premium.

However, you're correct that sometimes they're semantically important.
Fixed.

It now produces:

    filter (f . g) . $map f = $map f . filter g
