运行接口中存储的任何功能{}

I want to store a function with any parameters in an interface{} and be able to run it elsewhere.

So it could store a func(string) string or a func(int, int) string or etc, but I need to be able to call it later and be able to tell it what type of function it is. I tried to use .(func(string) string) and .(func(int,int) string), but got nothing.

Any help is appreciated.

Have you looked at the reflect package?

Particularly Type and ValueOf and Value.Call.
