 '''Debugging of type family patch:'''
  0. `boxySplitTyConApp` and friends must be able to deal with `orig_ty`s that have outermost type family applications; i.e., they need to try to normalise and possibly have to defer.  They also need to defer on skolems.  Consequently, they also need to return a coercion.  This , in particular, affects the treatment of literal lists, parallel arrays, and tuples in`TcExpr.tcExpr` is fishy.
+ 0. Fix export list problem (ie, export of data constructors introduced by orphan data instances):
+   * Change `HscTypes.IfaceExport` to use `Name` instead of `OccName`.
+   * Then, there is also no need for the grouping of the identifiers anymore; i.e, just use a flat list of `Name`s (but sort it to avoid spurious iface changes dur to re-ordering when re-compiling).
+   * We still need to have the name parent map, though.
  0. Fix core-lint breakage in cholewo-eval.
  0. The tests `tcfail068` and `rw` used to raise more type errors right away.  Now, we see less recovery.
