Eric Niebler did a very interesting discussion targeting Range
proposals for C++17.
I think it would be great inspiration for future improvements on
D ranges:
The shortcomings of classical C++ (begin, end) ranges:

The shortcomings of infinite ranges represented by (begin, end)
ranges: http://ericniebler.com/2014/02/18/infinite-ranges/
Fixing ranges by allowing begin type to be different from end
type, allowing Sentinel Ranges:

Making this new Range (called by the author as Iterable) capable
of dealing with infinite ranges:

How this discussion touches D ranges design decisions?
