[Haskell-cafe] Designing a DSL?

[Günther Schmidt]

Hi,

there are numerous examples on how to implement a DSL, but I haven't been  
able to figure out how to "design" one.

I mean I have a pretty good idea of the problem domain, I've coded it over  
and over again until I got it right. Now I'd like to express that part as  
a DSL instead of "hard coding" it as before so I can be more prepared if I  
need to change or amend it. Ideally I'd only have to change the  
interpreter, right?

And that I find to be the really tricky part, how do I *design* a DSL?
