Detailed Description

This class represents an incoming formal argument to a Function.

A formal argument, since it is `‘formal’', does not contain an actual value but instead represents the type, argument number, and attributes of an argument for a specific function. When used in the body of said function, the argument of course represents the value of the actual argument that the function was called with.
