+When we desugar [d| data T = MkT |]
+we want to get
+ Data "T" [] [Con "MkT" []] []
+and *not*
+ Data "Foo:T" [] [Con "Foo:MkT" []] []
+That is, the new data decl should fit into whatever new module it is
+asked to fit in. We do *not* clone, though; no need for this:
+ Data "T79" ....
+
+But if we see this:
+ data T = MkT
+ foo = reifyDecl T
+
+then we must desugar to
+ foo = Data "Foo:T" [] [Con "Foo:MkT" []] []
+
+So in repTopDs we bring the binders into scope with mkGenSyms and addBinds,
+but in dsReify we do not. And we use lookupOcc, rather than lookupBinder
+in repTyClD and repC.
