I have this defined function. I also have lenEq1, lenGt1, and a few
other variants. It works, but it just doesn't feel elegant.
Note: In case anyone gets the wrong impression, I am not suggesting
lazy naturals be the standard numeric type in Haskell, just that by
not going that way we have paid a cost in terms of elegance.
Thanks
