Railroad diagrams for Haskell?

Question

Anyone knows a book or a web-site that would feature a simple set of railroad diagrams for Haskell grammar?

Something like this but in English:

"Simple" is the key word here. Formal BNFs are too cryptic to be used as a cheat sheet.

Answer 1

There is some BNF in the Haskell 2010 report (especially in the "Syntax" chapter):

Note that most programs use language extensions which add syntax to the base Haskell language - e.g. the FunctionalDependencies extension. Also, GHC has added new syntax (most recently lambda-case / lambda-if). A list of syntactic extensions supported by GHC 7.6 (currently the latest) is available at:
