Go map of functions

Are you trying to do something like this? I’ve revised the example to use varying types and numbers of function parameters.

package main

import "fmt"

func f(p string) {
    fmt.Println("function f parameter:", p)
}

func g(p string, q int) {
    fmt.Println("function g parameters:", p, q)
}

func main() {
    m := map[string]interface{}{
        "f": f,
        "g": g,
    }
    for k, v := range m {
        switch k {
        case "f":
            v.(func(string))("astring")
        case "g":
            v.(func(string, int))("astring", 42)
        }
    }
}
