As you may or may not know, when you send a message to nil in Cocoa, it doesn’t do anything and certainly doesn’t raise any exception. You may or may not agree with the design, but we’ve all programmed just fine with this fact.

Having said that, what if you wanted the same behavior in Ruby?

NilClass.class_eval { define_method(:method_missing) {|*args| self} }

Is this a good idea?
