i'm writing function of following type: match :: [(string,a)] -> maybe (string, a, a) i want function traverse list of tuples, , determine if there tuples in first element (a string) same. if so, want return tuple containing string, second element in each of matching tuples. if there no matching tuples, return "nothing". if there more 1 matching, return first 1 finds. for example: match [("x", 3), ("y", 4), ("z", "5"), ("x", 6)] = ("x", 3, 6) match [("x", 3), ("y", 4), ("z", "5")] = nothing i'm thinking: match (x:xs) = if (fst x) = (fst xs) return (fst x, snd x, snd xs) --if no matches, return nothing thank help! what if there 3 or 4 tuples "x"? can't have variable-length tuples. maybe want return list: match :: [(string, a)] -> maybe (string, [a]) what if there several tuples match? want them all, or first? if want the...

what rationale behind assigning general type num => a 2 instead of defaulting specific type int or integer ? secondly have read @ many places 2 polymorphic value definition of polymorphism doesn't admit constrained variables. 2 polymorphic in haskell? 2 polymorphic can use whatever type of number like. num type class has function frominteger , used here. 2 frominteger (2 :: integer) . if 2 not polymorphic have write if wanted non-integer number, because there no automatic coercion in haskell (i.e. can't (1 :: integer) + (1 :: int) ). case fractional fromrational way. polymorphic type variables can have constraints. if not have constraints, called parametric polymorphism , if constrained , bounded parametric or ad-hoc polymorphism . see haskellwiki article on polymorphism . be aware, should not rely on type inference top-level functions or else may fall trap monomorphism restriction . example if write @ top-level of module: polymorphic = 42 ...
