Alternative for function overloading in Go?

Question

Is it possible to work similar way like the function overloading or optional parameter in C# using Golang? Or maybe an alternative way?

Answer 1

The idiomatic answer to optional parameters in Go is wrapper functions:

func do(a, b, c int) {
    // ...
}

func doSimply(a, b) {
    do(a, b, 42)
}

Function overloading was intentionally left out, because it makes code hard(er) to read.
