Proposed resolution:

This wording is relative to N3691.

1. Add to [optional.comp_with_t]:

   template <class T> constexpr bool operator<(const T& v, const optional<T>& x);
   

   -?- Returns: bool(x) ? less<T>{}(v, *x) : false.

Confirmed that this issue is resolved in the current Library Fundamentals working paper.

[ 2014-06-07 Daniel comments ]

This issue should be set to Resolved, because the wording fix is already applied in the last fundamentals working draft.

[ 2014-06-06 pre-Rapperswill ]

This issue has been reopened as fundamentals-ts.

[ 2013-09 Chicago: ]

Move to Deferred. This feature will ship after C++14 and should be revisited then.

Addresses: fund.ts

In [optional.syn] there is:

template <class T> constexpr bool operator<(const T&, const optional<T>&);

But I can find no definition for this signature.
