&& si and ?
O simpla intrebare pusa interpretorului Hugs ne spune ce tipuri au:
__ __ __ __ ____ ___ _______________________________________________

Type :? for help
Hugs> :t (&&)
(&&) :: Bool -> Bool -> Bool
Hugs>
Hugs> :t and
and :: [Bool] -> Bool
Hugs>
Deci: && este un operator care poate prmi doar doua (cel mult) argumente de tip Bool si calculeaza conjunctia lor logica. Iar and are ca argumente o lista de valoori Booleene si calculeaza conjunctia lor.
In cazul in care stiti bine limba franceza ati putea fi interesati sa rulati Haskell pe Mandriva Linux care de altfel are si suport pentru alte limbi.
Haskell ruleaza si sub Linux si sub Win-dos ! Fiti mai destepti si luati un computer cu Sistem de operare Mandriva Linux ! (Aceasta este o parodie a bannerului unei campanii publicitare, in spiritul dreptului la replica si al libertatii opiniei.)
