Btw if you want to see some interesting code:

import std.stdio;
import std.typetuple;

int Delay(alias Call, alias arg)() { return Call(arg); }

template Map(alias Call, args...) 
{
    alias TypeTuple!(
        Delay!(Call, args[0]),
        //~ Delay!(Call, args[1]),  // can't due to error
        2 * 10  // pretend we could
    ) Map;
}

int fun(int arg)
{
    return arg * 10;
}

void foo(Args...)(Args args)
{
    print( Map!(fun, args) );
}

void print(int res1, int res2)
{
    writefln("%s %s", res1, res2);  // writes 10 20
}

void main()
{
    int x = 1;
    int y = 2;
    foo(x, y);
}

Fun or what?
