12973	Example in docs for optional<T&> copy constructor is wrong	barry.revzin@…	Fernando Cacciola	"In the [http://www.boost.org/doc/libs/1_63_0/libs/optional/doc/html/boost_optional/reference/header__boost_optional_optional_hpp_/detailed_semantics.html documentation for Optional] in the latest version, and many past versions, the example in the copy constructor for `optional<T&>` reads:

{{{
T v = 2 ; T& ref = v ;
optional<T> init(ref);
assert ( *init == v ) ;

optional<T> init2 ( init ) ;
assert ( *init2 == v ) ;

v = 3 ;

assert ( *init  == 3 ) ;
assert ( *init2 == 3 ) ;
}}}

Both `init` and `init2` should be of type `optional<T&>`, not `optional<T>`. "	Bugs	new	To Be Determined	optional	Boost 1.63.0	Cosmetic			barry.revzin@…
