Background

• Being inspired by Typing Haskell in Haskell, I thought Parsing Haskell in Haskell, in the same spirit, would also be a good idea.
• I decided to start by trying to create A Lexer for Haskell in Haskell.
• Most of the work was done during a warm and sunny summer week in 1999.
• The final parts (nested comments and layout processing) were added last year.
