Maybe Haskell is much handier than I give it credit for, but it's
hard for me to imagine that it is as convenient as Python 3, even
without the cmp sort option...  (And I agree with you that getting
rid of sort's cmp in Python 3 was a bad idea.)

What's going on here?  Our lab recently hired a new postdoc who,
to our disbelief, works almost exclusively in OCaml.  And I hear
all this talk about switching to Haskell or Scheme.  I don't get
it.  Despite the elegance of these languages, the libraries are
not there.  It seems to me it would take forever to get the simplest
things done in these languages...
