You usually write a DSL in haskell as a library, using monads or arrows 
if it is the case, and exploiting monads and arrows syntax facilities. 
Names in libraries represent operations of the DSL, and do not (of 
course) necessarily compute results, but can do many things, including 
generating source code for another language - you can find a lot of 
information on the web, e.g.


One of the most known examples is FRAN (or the more up-to-date Yampa), 
but there actually are a lot of applications from very different
