Why are math.{trig} functions (still) not implemented?

Hi, I'm wondering why the trigonometric functions have (still) not been implemented. Are these float -> float (or maybe float -> float -> float for atan) fundamentally different/trickier to implement than, e.g., math.sqrt or math.fmod?

It seems these should be low-hanging fruit and allow some more applications of Pallene (certainly for me).

You are correct: these are low hanging fruit. Feel free to go ahead and open a PR if you want :)

I suspect one reason it hasn't been done yet was that we were waiting on ways to call existing Lua stdlib functions (#594), or a proper module system, so the math lib could be a library instead of compiler intrinsics. Until now, we've added new math functions as the need for them came up (e.g. some benchmark asked for it).

Thanks for the clarification @hugomg! I'm in crunch mode at work these weeks but I want to get on this when I emerge 😅
