Cool ^^ The number is jarring especially in a mathematical context but ultimately necessary, since we cannot detect the arity of functions.
Arc has absolutely no axioms for introspecting into function objects - it can only detect if the object is a function, and nothing else. I hope to rectify this in the Arc dialect I'll build for SNAP - there should be a ways to decompose a function to a function code object (potentially serializable!) and the closured data, as well as determine other bits about the function.
