haskell - Is name reuse the only advantage of type classes? - i trying understand type classes in haskell. i pose question using simple example: lets consider 2 datatypes, a , b . lets assume a1 , a2 of type a , b1 , b2 of type b . now let's assume want define functions check if a1 equals a2 , whether b1 same b2 . for have 2 options: option 1: define 2 equality functions using separate names : eqa :: -> -> bool eqa = ... eqb :: b -> b -> bool eqb = ... now if want check if a1 equals a2 write : eqa a1 a2 , b : eqb b1 b2 . option 2: we create a , b instances of eq typeclass. in case can utilize == sign checking equality follows. a1==a2 b1==b2 so, question : far understand sole purpose of existence of type classes can reuse function name == equivalence checking function, shown in alternative 2. if utilize type classes not have utilize different function names same purpose ( i.e. checking equality). is correct? n...
