-\subsubsection{Permutative rewrite rules}
-
-A rewrite rule is \textbf{permutative} if the left-hand side and right-hand
-side are the same up to renaming of variables.  The most common permutative
-rule is commutativity: $x+y = y+x$.  Another example is $(x-y)-z = (x-z)-y$.
-Such rules are problematic because once they apply, they can be used forever.
-The simplifier is aware of this danger and treats permutative rules
-separately. For details see~\cite{isabelle-ref}.
