"derived-type-spec" is a grammar production associated with types.  I don't know how that can be relevant here.  And I think that `UnwrapExpr<Constant<SomeDerived>>(x)` will always be null -- if the subexpression is a structure constructor, it's not a `Constant` -- so the effect is to just return `false` for all structure constructors.  So I don't understand this part at all.  What are you trying to accomplish here?
