Hi,

I believe it's aligned for sequence containers, and subscript returns `reference` for a non-const container there, regardless of value category.

Cheers,

To be honest, this prompts the question as if this was an oversight
(does std::array predate move semantics?) or a deliberate design
decision to align with e.g. std::vector.

(I can understand why std::vector operator[] hasn't been changed to
return rvalue references invoked on a rvalue vector.)

Thanks,
