I can't recall I ever had a use case where I wanted to do some operation 
on a collection and then transforming it to another type of collection. 
I just want to perform the operation, then get back a collection of the 
same type:

int[] a = [3, 4, 5, 6 ,7];
a = a.filter!(x => x < 6);

Since that's not possible with the way ranges are designed I was 
thinking if it at least would be possible to have a generic interface to 
get the a collection (of the same type) out of the range.
