Ha!  I now know the exact amount of effort to add parameter validation 
... Change the method_missing definition in Recorder to read:

      def method_missing(sym, *args, &block)
        @mock.should_receive(sym).and_return(&block).with(*args)
      end

(i.e.  add ".with(*args)" to the end of the line).

Not only do you get parameter validation, but the full range of 
constraints available to the "should_receive" sytle of specification.

For example:

   FlexMock.use do |mock|
     mock.should_expect do |recorder|
       recorder.add(Integer, 4) { |i, f|
         i + f
       }.at_least.once
     end

     # Test fails if mock.add is not called at least once with
     # integer for the first argument and the number 4 for the
     # second argument.
   end
