Any idea why the Tails library may be contributing to longer compile time?

For future reference I was able to compare a quick wrapper NIF vs Tails for a few different sizes of class lists. Got about a 2-8x speed boost depending on size with identical outputs and without the slow compile. I’ve never written a hex package but might just throw it up when I have time.

I do agree there should just be a universal tool for this, but right now it’s useful to me without having to mess around with layers too much.
