Re: metamap being zero cost I thought there were no zero cost abstractions in C++? https://youtu.be/rHIkrotSwcc https://youtu.be/rHIkrotSwcc Still, it isn’t

  Yes zero cost is subjective. It has a cost at least at compile time. But you can see metamap is a like loop unrolling for objects (if you think loop unrolling is zero cost then metamap too).
