Cosmetics in SpecConstr
SpecConstr currently uses substExpr for tiresome reasons to do with GADTs. Unfortunately the substExpr generates some WARNINGS (when DEBUG) is on, because we aren't adding all the in-scope Ids to the in-scope set of the substitution. When we move to FC these substExprs will go away, so I'm not going to worry about this now.
