Have been beginning to strictly type check more and more, and I'm wondering, how do Type Parameters work?
How would you, say, define a function that make it's own function of which requires a type similar to how Signal+ does?
Below is my current experience with it; not even sure if it works ingame yet lol. but I know the type checking does
