I know ruby is dynamically typed, but a method is implemented to work with certain type of parameters. If one wants to invoke a method dynamically using reflection, how do you go about finding this information so it is invoked with right type of parameters? One can not expect to know this information before hand if a class/module is going to be dynamically loaded. In Java or C#, you can get this information on parameters so you can supply the right type of values to a method that is invoked dynamically. Any suggestion? Thanks.

The last line of the 3rd code box should be:

m.instance_variable_get :@i #=> nil

There is no accessor method named i on the object.
