D overloading nested functions

original text

void main(){
    
    template bar(){
    
        void bar(int){
    }
        void bar(float){
    }
    }
    bar(1);
    bar(3.14);
}

This is really a That's a good idea .

import std.stdio;

void main()
{
    
    template funcs()
    {
    
        void foo() {
     bar(); }
        void bar() {
     writeln("Hello world"); }
    }
    mixin funcs;// Plug in templates , Call any function inside .
    foo();
    bar();
}
