	Introspection/reflection/whatever is looking at the metadata
for the code not the code it self... I think a brian storming session tonight
should resolve much of this (at least at the philosphical if not "praticle"
level [in the case of language design there is not much difference]).

	Design/definitation/implimentation/whatever in the terms of
languages is nothing but many faces of the same coin.

	If properally designed/implimented this should be invisible

	Depends on the area your addressing there are no absulutes
including this statement.
