Hi,

I would like to gauge interest in a library that makes the usage of flag-like enumerations safer. The library is called Boost.Flags, and its key features are ... Example on Godbolt: https://godbolt.org/z/qbojncnd7

From the reading of the docs I gathered that the library relies on operators in the global namespace, rather than using a macro to define operators in an enum's namespace. This has a certain flaw: https://godbolt.org/z/xePjK3es6

The described flaw can be avoided by either including flags.hpp before `foobar` or by `using ::operator |` in the enums namespace. (https://godbolt.org/z/rT5678n4f) I could add a macro the enables ADL for the current namespace, e.g. #define BOOST_FLAGS_ENABLE_ADL_FOR_NS \ using ::operator| \ using ::operator& \ using ::operator^ \ ... and so on
