It is an EXCELLENT utility module, but I tend to use it and (in patches I super love online/conversation in this very thread) see it used for its base functions more than its more hyped self-patching possibilities.
Maths is like Exhibit A, B, and C for me that I should really spend way more time learning the modules I have - which includes spending the requisite # of hours with them until complex, arcane functionality becomes simple muscle memory - before I think about expanding my rack. It’s certainly a module with seemingly endless exploration possibilities, and that illustrated guide is just scratching the surface.
(Edit for clarity: I’m saying this mostly for myself, not anyone in this thread. I assume most everyone here is a deep sea modular diver)
I found this well-written and helpful, with lots of links to dive into:
