disentangling (c) => c()

I have an issue with : (c) => c() which I found here and there. I understand that it defines an anonymous function with an untyped parameter, c. But then it seems to refer

  • to a parameter-free undefined function c(), i.e. having the same name as the parameter of the initial-anonymous function,
  • or to its own parameter c as if this very parameter were a parameter-free undefined function it-self.

I'm pretty sure that I did not get it right and that I miss the point, but any hint would help to untangle (c) and c(), and grasp what the function ends up doing for real.

It is an anonymous function that gets something named c. It then calls what it gets as if it were a function. That implies that the compiler figured out that it either is a function with no parameters, or it is a dynamic. Otherwise the compiler would have complained.

So in english: an anonymous function that has a parameter named c. The type of that parameter is "function with no parameters". It then calls the function it just got as argument.
