Thanks, I'm glad you like it.
I see that the windows cmake build workflow is failing, and I honestly don't know why, since the one on linux runs fine. Any ideas?

Looks like it's choking on the fold expression. Lemme look into it.

Update: Looks like it's a compiler bug: https://stackoverflow.com/questions/66070211/when-are-fold-expressions-as-template-parameters-allowed

I've verified by compiling against C++20 at-desk. Thanks again Microsoft...
