  * Solving of equalities (`TcTyFuns`):
   * #2219, #2235, #1775 & test `GADT1` (bogus occurs check failure - in both bugs, the loop is through a TF)
-  * #2202 (Uses `a ~ MeshVertex a b` in `normaliseWantedDicts` w/o the occurs check kicking in; also occurs in 6.8.2 and the program doesn't mention TFs, so need to merge):
-    * Should `eqInstToRewrite` already check for and return whether the equality is cyclic in a bad way (i.e., without intervening tyfam)?  (Would that be less efficient?)  In any case, document the invariants.
-    * `rewriteWithOneEquality` should uses `eqInstToRewrite`
    * #2448 (givens not properly used in superclass entailment check)
    * #2102 (superclass equalities)
