[Haskell-beginners] Error Loading Stdm.lhs in Haskell platform 2012

[Eugene Perederey]

What version of ghc are you using?
In recent versions ghc doesn't support pattern matching of expressions
like (n+1).
You can rewrite that factorial function as
 factorial n = n * factorial (n-1)
instead.

best,
Eugene
