<para>The simplifier no longer simplifies rewrite rules.</para>
<para>
Starting with 7.10.2 GHC would simplify both the left- and
right-hand-sides of rewrite rules, causing a variety of unexpected behavior.
Simplification of the LHS resulted in various rules to fail to fire (<ulink
href="https://ghc.haskell.org/trac/ghc/ticket/10528">Trac #10528</ulink>, in
particular affecting the widely used <literal>text</literal> library)
whereas rewrites of the RHS broke some of the more exotic uses of rewrite rules
(e.g. HERMIT, <ulink href="https://ghc.haskell.org/trac/ghc/ticket/10829">Trac
#10829).</ulink>
