RING: (f°g)(x) === f(g(x))
what would be the advantage of this? other than seeming harder to read? i tried to read up on rings in math refereces and didn't really understand anything.
If you look up "ring" in mathematical references you have to be a bit careful, since there is a term "ring" in group theory that refers to a set with some particular properties. That kind of "ring" has nothing to do with the "ring operator" (which is also known as the "composition operator", and does just that: compose two functions into one).
