I'll get to the point here:

How about we explicitly write in the C++26 Standard that T[len] and
array<T,len> are ABI-compatible, and also provide two functions:

   stdarray_to_array
   array_to_stdarray

, both of which return a reference to an object that doesn't
malfunction where you have anti-aliasing optimisations.
