An object of type \tcode{optional<T>} at any given time
either contains a value or does not contain a value.
When an object of type \tcode{optional<T>}
\defnx{contains a value}{contains a value!\idxcode{optional}},
it means that an object of type \tcode{T}, referred to as the optional object's \defnx{contained value}{contained value!\idxcode{optional}},
is nested within\iref{intro.object} the optional object.
When an object of type \tcode{optional<T>} is contextually converted to \tcode{bool},
the conversion returns \tcode{true} if the object contains a value;
otherwise the conversion returns \tcode{false}.
