Possible to iteration on an operator[] overloading object?

[LukyGuyLucky]

Given below code snippet,is it possible to iterate on foo other than foo.x?Thanks.
Maybe this is just a silly idea.

module op_overloadings02;

import std::io;

struct Foo
{
	double[] x;
}

fn void Foo.get_ref(&self,usz i,double new_val)@operator([]=)
{
	self.x[i]=new_val;
}

fn double Foo.get(&self,usz i) @operator([])
{
	return self.x[i];
}

fn void main()
{
	Foo foo=Foo{.x={1.0,2.0,3.0}};
	
	foo[0]=4;
	foo[1]=5;
	foo[2]=6;
	
	for(int i=0;i<foo.x.len;i++)
	{
		io::printfn("Index #%d\telement value: %d",i,foo[i]);
	}
	
	foreach(i,value:foo.x)
	{
		io::printfn("Index #%d\telement value: %d",i,value);
	}
	foreach(i,value:foo)  // it is not possible to iterate on an expression with c3c current vesion(0.62 svn)
	{
		io::printfn("Index #%d\telement value: %d",i,value);
	}
}

Overloading []= only allows foo[i] = 213, it doesn't do anything else. You're also overloading [], but not len, so you don't get foreach

Thank you. I get it

fn usz Foo.len(&self) @operator(len)
{
    return foo.x.len;
}

Yes.
