The GSL may be the little list of types and aliases laid out in these pointers. As of the creating, their specification herein is simply too sparse; we intend to include a WG21-type interface specification to make certain unique implementations concur, and also to suggest to be a contribution for feasible standardization, topic as common to whatever the committee decides to just accept/increase/alter/reject.
See GOTW #a hundred and cppreference for the trade-offs and additional implementation specifics related to this idiom.
