What I've always found funny about pleac is that none
of the examples are actually Haskell, but some weird
Haskell-with-oo-features. Does anyone know what
language it is?
Here are some examples:
password = [1..8].mapM (\_ -> rand (0, chars.length
-1) >>> (chars!))
-- in haskell, regexp are first class, then can be
appended, sometimes easier to read
m0' s = .... (s ==~ dec_number) ....
They are actually Haskell, but notice the appendix:
http://pleac.sourceforge.net/pleac_haskell/a1102.html
It's Haskell with a completely bizarre prelude. No real new features
were added to the language itself.
Replacing composition with reverse function application is a waste of
operator symbols.
Personally, if I was going to change (.), it would be to define it as
fmap, which (as a number of people, myself included, have pointed out)
together with the instance of Functor for ((->) e) would generalise
ordinary composition, map, liftM, etc.
