[Haskell-cafe] Design of a DSL in Haskell

[Joerg Fritsch]

Rusi,

I have "read" Fowler's book.(that is focusing on Java by the way) and could not find the answer there, I think it is a typical textbook.
I think this is a good start by the way: http://www.cse.chalmers.se/edu/year/2011/course/TIN321/lectures/bnfc-tutorial.html
