"foreach" statement, it takes a range only.

So is there any way other than returning an array from a function 
that is to be passed foreach statement? So I could write like 
that:

Iterator iter = new MyList();

foreach(item; iter){
}


Otherwise I will need to write like that:

foreach(item; iter.getArrayOfAvailableItems()){
}

Unless you are just experimenting, it's better to not go against 
a language and its std lib.
