Subject: Re: [ANN] Ducktator - A Duck Type Validator

This might be useful in testing. Thanks for the hard work! I can
imagine a scheme where during debugging I do exhaustive validation of
all objects passed to each method. This way I know if the object
doesn't respond to a method - I don't have to wait for a call to fail.

Incidentally, I have often wondered if there might be a tool that
could generate a report of the methods a certain method might try to
call on a specific object. For example:

def doSomethingAmazing(fridgeMagnet, pieceOfString, brownPaperBag)
  pieceOfString.tie fridgeMagnet, brownPaperBag[5]
  pieceOfString.unravel
  fridgeMagnet.stickTo self.fridge
end

.. produces ..

doSomethingAmazing
--------------------------------
fridgeMagnet: stickTo
pieceOfString: tie, unravel
brownPaperBag: [


.. so if I am implementing an object to pass to doSomethingAmazing, I
know what it expects.
