    Hey there,

Is there a "constexpr regression library" somewhere to be perused?

I've been writing ornate const expressions, and am finding them to be a similar battle ground to getting things to run across different compilers in 2000.

Is there some "known to work" example set?
And a "known to not work, but should" example set?

I would be willing to add a few to both.
