Layout mapping types expose extents_type, not extent_type; the latter is a member of extent_slice. As written, IT and M_rank in the Let clause name an undefined member.

Layout mapping types expose
extents_type, notextent_type(the latter is a member ofextent_slice). The Let clause in[mdspan.sub.map.sliceable]definesITandM_rankvia the undefined memberM::extent_type, making the subsequent sliceable layout mapping requirements uninterpretable.The same subclause uses
LayoutMapping::extents_type::rank()andSM::extents_type::{rank,index_type}correctly elsewhere.
