Why ranges don't return vectors?

There's no reason you can't do that. In fact, some ranges already 
do this. Take a look at std.stdio.File.byChunk and byLine. This 
isn't appropriate for all ranges, though. Like arrays, for 
instance. You want to be able to access single elements and do 
things with them, otherwise the abstraction is pointless.
