It doesn't have to be a problem that the string is copied each time. If you
have, e.g., functions
f1, f2, ..., fn :: String -> String
and do something like
f1 (f2 (... (fn string)...))
then string and the intermediate data can be removed by the garbage collector
as soon as they are not needed.
Unfortunately, from your message it's not very clear to me what exactly you
mean, and, unfortunately again, I'm not an expert in Haskell memory
management.

Indeed, they all look very non-elegant, and I think, there is a better
solution.
