Hey Jonathon,
Based on the last email you sent, it seems like you're not quite satisfied
with the responses.
And for good reason.
It turns out that there is more to
length (2,3) = 1
sum (2,3) = product (2,3) = 3
than just the offending Traversable instance of the tuple pair (,).
Would you mind resending your first email of Apr 23 to the haskell-cafe
mailing list?
If you do so, I'll contribute by opening a discussion of the Functor
instance.
Best,
Kim-Ee

I've seen many threads, including the one going on now, about why we need to have:
length (2,3) = 1 product (2,3) = 3 sum (2,3) = 3 or (True,False) = False
but the justifications all go over my head. Is there a beginner-friendly explanation for why such seemingly unintuitive operations should be allowed by default? _______________________________________________ Beginners mailing list Beginners@haskell.org javascript:; http://mail.haskell.org/cgi-bin/mailman/listinfo/beginners
