[Haskell-cafe] map and list comprehensions

[John Peterson]

I think the point was that all syntax (like list comprehensions or
pattern matching) in Haskell is tied directly to the Prelude.  So [ f
x ...] is ALWAYS using the Prelude definitions of things while "map"
could be hidden and redefined.  The inability to change the meaning of
constructs expanded from syntax as considered a bug by some, a feature
by others.  And I don't rember where Paul stood on this ...

And the change between list / monad comprehensions was debated
intensly by the committee at every step.  The only real argument
against monad comprehensions was that they confuse beginners with
overloading.
