-The role of that original ``before`` was to intercept ``Listen`` actions,
-while leaving all others well alone. The role of the ``before`` in the
-``Prop`` class is broader: to intercept (a) ``Examine`` actions, and (b)
-all the rest. If the action is ``Examine``, then the ``return false``
-statement means that the action carries on. If the action is ``default``
--- none of those explicitly listed, which in this instance means *every*
-action apart from ``Examine`` -- then the ``print_ret`` statement is
-executed, after which the interpreter does nothing further. So, a ``Prop``
-object can be EXAMINEd, but any other action addressed to it results in a
-"no need to worry" message.
