[Haskell-beginners] type T' = T a b c

*problem*: given type T with a few parameters e.g. T a b c some functions where this type is passed to, are agnostic to a, b, c i.e. accept T with any of a, b, c processT::T a b c -> () when either number of these parameters or T change (c is dropped or d is added: T a b c d), signatures of every function where T is passed to, need to be updated. *question*: is this possible to specify type synonym T' so that it may be passed to parameter (a,b,c) - agnostic functions so: processT::T' -> () ?
