I could instead imagine the usefulness of alphaPos :: Alphabet ->  Char ->  Int which indicates what position a given character is in its alphabet (alphaPos English 'a' == 1, for instance), and its inverse alphaFromPos ::  Alphabet -> Int -> Char.

I find myself doing something along these lines (but usually with 'a' -> 0) often enough that I would support adding such functions.

But if I am trying to read a number from a String, I would almost certainly want it to fail on encountering any non-hex digit, rather than producing a strange number.
