I forgot

    append = (++)

We also need to address another elephant in the room... those pesky tuples
and their special privileged non-wordy syntax!

   pair = (,)

   triple = (,,)

   quadruple = (,,,)

   quituple = (,,,,)

   sextuple = (,,,,,)

   septuble = (,,,,,,)

   octuple = (,,,,,,,)

If Haskell were invented in this century's EU Haskell source code would be
littered with €s instead of $s but then again I wonder why £ wasn't picked.
But I digress. We can kill two birds with one stone here:

   apply = ($)

   strictApply = ($!)

   compose = (.)


It's fun to imagine how code using those definitions would like! But it's
still a -1 for me, sorry!
