Subject: getting the name of arguments a method takes

I am wondering if there is a way to programatically get the name of the 
arguments a function take.

Say, I have this code:
  class MyClass
      def my_fct(a, b, c)
     end
  end

Now, I can easily get a handle to the method 'my_fct' using:
  mc = MyClass.new
  meth = mc.method(:my_fct)

But how do I get to the list of arguments of 'my_fct' ? I couldn't find 
anything like:
  meth.arg_list
which would return [ :a, :b, :c ], or something like that.

Is this even possible in ruby ?

-Didier
