Also, lazy evaluation has the risk of getting confusing as there's a lot
of escaping. Consider:
int[] arr = [ 1, 2, 3, 4 ];
auto squares = map!("a * a")(arr);
arr[] = [ 5, 6, 7, 8 ];
Now iterating squares will see different numbers than the original ones.
This part bothers me. Though it's hard to tell how much danger it would
impose in practice.
I could also see it being useful in some situations. But, yes, it is
unexpected.
