Every time you create a function of “multiple arguments”, you really create a curried function. Which means that let add x y = x + y is a sugar for let add = fun x -> fun y -> x + y

That is, when you partially apply a function, the resulting function is no longer polymorphic. That's why you see '_weak1 in the second type signature. When you include the fmt argument, you help the type-checker recognize that polymorphism is still present.
