I also did some work on this, see http://code.google.com/p/sympy/issues/detail?id=1754#c2 I think it's better to keep ArgumentIndexError and define it properly than to remove it. Concerning DiracDelta(1).fdiff(1), note that DiracDelta(1) is just S(0), so this raises the question of the purpose of having Basic.fdiff defined at all.
