Of course I would only vibe-code Sane C++ Libraries!

I wonder if I should capitalize on this by distributing them as isolated single file libraries...

std::launder is so 2024

This is going to be hard!

Fun fact: I was just incidentally thinking right now about using thread_local static to store a memory allocator.

I have been slapping volatile where I think it makes sense to force the optimizer think twice about making weird assumptions around that code.
Hopefully this will not be so bad performance wise.
I could maybe replace that offset == 0 conditional with some branchless code to improve things further...
