Just as a matter of idle curiosity, is there a particular reason for tuples starting at element 1 (fst) whereas lists start at element 0?

'fst' (first) is an ordinal. It actually corresponds to the cardinal 'zero'. The element at zero is the first element. The element at 37 is the 38th element. It's quite consistent. -- Ashley Yakeley, Seattle WA
