I can't think of anything in the pure concept of Domain Specific Languages that would make them hard or impossible to debug. You'd only have to write a good debugger for the language. > And how does it apply to Haskell? A DSL embedded in Haskell has the advantage (and disadvantage) of being normal Haskell code, hence the normal Haskell debuggers will work. However, if the EDSL is presented as an entirely new language then non-Haskellers will obviously have problems understanding the generic Haskell debugger and error messages.
