The casts inside Flags iteself are needed because it has to support both scoped and non-scoped enums. For scoped those are absolutely necessary and behave as intended. With c++11 enums can be forward declared since the standard now defines the underlying type to default to int32_t (iirc) - and allows manual specification in forward declaration (only for scoped..). Additionally the trait was added to resolve manually specified underlying types. I am sorry there is nothing to fix there.... just to add but more on that on monday i guess.
