That's an additional step we can take, but if clang-tidy has a 
modernize-scope-enums (or we could write it), then it would be 
preferable to just automatically port all users instead of writing code 
that keeps unported code running. The main issue isn't the scoping, the 
main issue will be the missing implicit conversion to underlying_type.
