Operator overloading like using + on strings or adding n-space vectors to other n-space vectors is at least convenient, isn't it?

But at the same time, something that could be achieved by something like Haskell typeclasses, e.g. a "concatenatable" typeclass - which then gives you more polymorphism for free than you originally anticipated!

Defining an instance of "concatenable" (eg, Monoid) for some type in Haskell is pretty much isomorphic to overloading some free function (or operator) on some type in C++. It's the same "amount of polymorphism" either way, namely ad-hoc polymorphism.
