The underlying idea appeals to me.
In the next few days, I will read your proposal in more detail to give you
a complete feedback, but for the moment I will focus on the basic design.
I think you are bitting off more than you can chew, among new classes, new
functions, and new concepts. Your implementation would be great for a
custom library that provides containers for linear algebra operations, but
it is too restrictive and full-bodied for an update to the C++ standard.
I do not agree with introducing new classes that involve direct memory
management, in particular if there are two versions that provide static
memory and dynamic memory separately, because I believe they are redundant
with the already-existing STL containers, such as std::vector and
std::array (it is effectively used in your implementation of fixed size
I think you may avoid this by creating adapters, like std::flat_set /
std::flat_map, that provides different interfaces to perform linear algebra
operations and do not worry about anything at lower level.
