Thanks Peter I don't know to what I was thinking :(
An enum (scoped or not) is always implicitly convertible to its
underlying type.
Andrey, why this implicit conversion must be removed? What is wrong with it?
- operator enum_type() const BOOST_NOEXCEPT { return get_native_value_(); }
I have added the line you removed and all the test pass. Which case need
to remove this implicit conversion?
Best,
Vicente
