How do I return a function and then call it later?

So let's say I have this structure a and a void method that takes this structure as a parameter. How can I return a void method using another method and then call it later?

The code I have is as follows:

struct Script{
    //variables
}

void foo(Script e)
{

}

function getfoo()
{
    return foo;
}

void main(string[] args)
{

    writeln("Hello World!");
    stdin.readln();
}

import std.stdio;

struct Script
{
    int x, y;
}

void foo(Script e)
{
    writeln("Got: ", e);
}

void function(Script e) getfoo()
{
    return &foo;
}

void main(string[] args)
{
    auto func = getfoo();
    func(Script(1, 2));
}
