I thought that the original question was about using some kind of uniqueness type system at an intermediate stage during compiling. Haskell would still have no uniqueness types but the compiler would infer uniqueness types internally and use the uniqueness information it gets from this. > -Jan > [...] Best wishes, Wolfgang _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
