I think it belongs in the HsSyn syntax tree. The RdrName for (say) Prelude.map is the same RdrName, whether or not it looks like `Prelude.map`.

One of the major headaches is the decorations on a RdrName. What I mean by this is that an item appearing in the AST as a RdrName may have parens or backquotes around it, and may have a preceding keyword out of [forall, pattern, type]. I am slowly teasing out the contextual requirements to determine these, but it seems that they should be captured directly in the AST already. And not as API Annotations. So the question is, does it make sense to do this? Does it belong in the OccName or the RdrName if so? Alan
