+Note [Unique OccNames from Template Haskell]
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The idea here is to make a name that 
+  a) the user could not possibly write (it has a "[" 
+     and letters or digits from the unique)
+  b) cannot clash with another NameU
+Previously I generated an Exact RdrName with mkInternalName.  This
+works fine for local binders, but does not work at all for top-level
+binders, which must have External Names, since they are rapidly baked
+into data constructors and the like.  Baling out and generating an
+unqualified RdrName here is the simple solution
+
+See also Note [Suppressing uniques in OccNames] in OccName, which
+suppresses the unique when opt_SuppressUniques is on.
