The GSL would be the small list of sorts and aliases laid out in these recommendations. As of this writing, their specification herein is just too sparse; we intend to include a WG21-design interface specification to ensure that diverse implementations agree, also to suggest like a contribution for doable standardization, matter as typical to Regardless of the committee decides to simply accept/strengthen/alter/reject.
