Subject: Get formal parameter names of a method?

Is there a way to reflect on a method to get the declard names of the 
parameters?

class Equipment

 def install(tool, packaging)
 end

end

I can do this:

m = Equipment.new.method(:install)
m.arity  # => 2

I want to somehow find out that the client code has declared the 
parameters named 'tool' and 'packaging'.

Is this possible somehow?  I feel like it should be, but I can't quite 
figure it out.

Thanks!
Jeff
