I am not sure where you imagine this on-the-fly stuff occurs. The
solutions I have presented build a compile-time look-up table. This
table does not need to be a member of the tuple.

This, like many of your arguments, focus on premature optimization.
Consider the following implementation:

Notices how the compiler has no problem optimizing this code even at
the lowest optimization level.

I do not know how to put this nicely, but these discussions feel more
like mentoring than standardization.
