Is implementing opCall(size_t) for structures such as array containers

I can't find any documentation on the subject on when opCall should be
defined to enable foreach (isIterable).
opCall is not related to foreach. It's used to overload the call
operator, i.e. ().
struct Foo
{
void opCall() {};
}
Foo foo;
foo();
Are you thinking of opApply [1]?
