Hi,
Is there a reason why we can't allow:
optional<int&> opt;
Also, is there a reason why we can't allow:
variant<int&, double&> var;
IIUC, internally, it's just a matter of storing a boost.reference_wrapper
if T is a reference.
In as much as tuple<int&> is allowed, I see no reason why optional
and variant can't allow references.
Am I missing something?
TIA,
