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
