Issue created Apr 06, 2013 by Krzysztof Gogolewski@monoidalDeveloper

"main function" is not a function

A module without main gives an error:

A.hs:1:1: The function ‛main’ is not defined in module ‛Main’

However, main in Haskell is not a function. This is often a cause of misunderstandings, for example see IRC discussions or Conal Elliott's "Everything is a function in Haskell". I suggest changing this to:

A.hs:1.1: The IO action ‛main’ is not defined in module ‛Main’
