Other than aesthetics, the reason I don't like the idea of fully scoping these types, at least without a comment, is that the error is triggered by some other code gets included first, and has nothing to do with this code -- there's nothing actually wrong with the original code.  So it could/would be confusing for a reader later on wondering why you needed to fully scope these types, and not others.
