You can use TypeTuple for static foreach.

void foo(int x)()
{
	import std.stdio;
	writeln(x);
}

void main()
{
	import std.typetuple;
	foreach (x; TypeTuple!(1, 2, 3))
		foo!x();
}

Notice that the loop variable x is used as a template parameter 
at compile time. The code expands to:

foo!1();
foo!2();
foo!3();
