oheimb [Fri, 31 May 1996 19:34:40 +0200] rev 1777
renamed le_0 to le_0_eq, to avoid confusion with le0, supplied an experimental thm Suc_le_eq, but commented it out

oheimb [Fri, 31 May 1996 19:12:00 +0200] rev 1776
moved mem_simps and the corresponding update of !simpset from Fun.ML to Set.ML, as there have been unnecessary proofs of anonymous thms, which could not be removed (by name) from the !simpset where necessary. All these thms except singleton_iff were already proved in Set.ML. therefore in Set.ML: New version of singletonE, proof of new thm singleton_iff
