Public Instance methods
arguments()

Resolves the arguments of the method to have an identical signiture —useful for preserving arity. 

  class X
    def foo(a, b); end
    def bar(a, b=1); end
  end

  foo_method = X.instance_method(:foo)
  foo_method.arguments   #=> "a0, a1"

  bar_method = X.instance_method(:bar)
  bar_method.arguments   #=> "a0, *args"

When defaults are used the arguments must end in "*args".
