Comment (by edsko):
So actually I agreed with you that the special case was undesirable, which
is why I had (for types, not yet for expressions) got rid of rnHsType
completely, and defined only rnLHsType. This way the exceptions you
mention are taken care off statically, which is much better.
Your suggestion is an alternative; I thought about it but I thought I'd
need to add a new constructor to HsExpr/HsType/Pat/..; didn't realize that
I could use the constructor for parens. Do you prefer I use HsPar and co
instead of removing rnHsExpr (rnHsType, ..)? It certainly would be a less
intrusive change I guess.
