How can I get built-in operator as a function?

Question

The goal

How can I get a built-in operator as a function? I want to take advantage of functional programming. I have some files with vectorizing functions (eg. Remap[inT any](sl []inT, f func(inT) inT)), which take a scalar function to apply on every element of one or two slices.

I know I could:

func eq(a, b int)bool{
   return a==b
}

and hope that after inlining there'll be no overhead.


But I prefer a short, performant & consistent way, if exists.

• In Python 3 I would:
  int.__eq__
• In Rust I would:
  i32::eq
• In C++ I would:

   #include <functional>
   /*code here*/
   std::equal_to<int>()

How would you achieve this in Go?
