The foreach loop is actually not important.
void f(lazy void dg)
{
dg();
}
void main()
{
void foo() { Stdout.formatln("o hai"); }
f(foo);

I think this is working correctly:
take this example:
import std.stdio;
void fn(lazy int i)
{
writef("%d\n", k);
auto j = i();
writef("%d\n", k);

{
if (arg->typ
