extended foreach?

[Mandel]

Hi,

I like to know if this feature request is even feasible
and what others think of it, of course.

class Foo {
   int opApply(int delegate(ref Type [, ...]) dg, float f, char[] s) {
       /*...*/
   }
}

float f = 1.5;
char[] s = "abc";
foreach(x; xs; foo; f, s)
{

}

The idea is to pass additional values from foreach to opApply.
Would be great to filter values in opApply for example.
(or even chaining foreach in opApply...)
