No way to construct empty Variant

[MKostyukhin]

Based on the description the default ctor should construct an empty variant value:

**
     * \brief Construct an empty variant
     *
     * Construct an empty variant
     */
    Variant();

hasValue method always returns 'true' even for the following simple scenario:

assert (Variant<char, int>{}.hasValue() == false); // expectation to have an empty variant here

and there is not bad_cast exception

const auto value Variant<char, int>{}.get<char>();  // there is no `bad_cast` exception, why?

Could you please clarify what is an excepted behavior?
