program. What will I do.
Good question. I've had a bad time with this, some in this list proably got
tired of me saying the same thing over and
Not really a Haskell question, but someone here might know the answer...
Suppose you have two morphisms f : A - B and g : B - A
such that neither (f . g) nor (g . f) is the identity,
but satisfying (f . g . f) = f. Is there a conventional name
for this? Alternately, same question, but f and
