This gofer is a fork of Mark Jones original with some additions and modifications, the most visible one being the Dijkstra dot for function application. See Notational Conventions – pg 8 onwards.
I used to call it pugofer since I was using it to teach when at Pune University in the early 90s.
Mark Jones is gratefully acknowledged for this pioneering work.
To see how source looks with these changed syntaxes, look at the standard prelude: pustd.pre.
The alternate prelude pusimple is particularly neat for those who feel the need to grok Hindley-Milner before getting into typeclasses. With that you’ll get, for example:
? :t (+) (+) : Int -> Int -> Int ? :t (==) (==) : a -> a -> Bool
You can switch back to classic Haskell syntax with
? map.(1+).[1,2,3] [2, 3, 4] : [Int] ? :s -S ? map (1+) [1,2,3] [2, 3, 4] :: [Int]
There is no configure to run.
Windows seems to build with mingw for 32 bit but not 64.
Justifications for these changes are explained in Notes on Notation

Evidently at the end of his life Dijkstra did support FP
