Will there be operators for these types? or will they be externally
defined?

That CompileTimePointConcept<T[N]> seems quite interesting but how
much use can it really be?

The problem is every algorithm has its own set of requirements for
what a point must be able to do/provide. Taking the approach mentioned
in the DG video from a previous thread (continually simplfying templated
inputs into routines) leads me to believe the most general point concept
would be any empty class.
