Re: [Haskell-cafe] putting the result of a function in `infix` declaration

Related to Karl's Template Haskell suggestion you could also have a look at quasiquotation: http://www.haskell.org/haskellwiki/Quasiquotation The GHC documentation has an example of a expression quoter: http://www.haskell.org/ghc/docs/latest/html/users_guide/template-haskell.htm...

In a more general way, let us suppose I have a Haskell library able to perform some calculations: how to use it in a pre-processing step, before compilation of the executable?

You are looking for Template Haskell.

http://www.haskell.org/haskellwiki/Template_Haskell

I'm not sure how up-to-date the wiki is, but it should give you the general idea.
