We've been seeing similar attempts recently, all attempting to fill a long overdue gap: the composability of algorithms in the standard library. At this point, there exists a TS [1] for ranges [2] along with an implementation [3]. It will be a thin layer on top of the iterator-based standard library, sometimes dubbed "STL2." On the one hand, it's great to new attempts to compose algorithms mushrooming, but on the other hand it would be great to see more aligned efforts to collaboratively push forward the TS and its implementation. [1] A technical specification (TS) can be thought of as a self-contained mini standard that vendors can implement, but do not have to in order to be "standard-compliant". A is a promising candidate for future inclusion into the standard, however.
