             Bug #: 54237
           Summary: [C++11] Make more tuple-related functions constexpr
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: zeratul976@hotmail.com


Many tuple-related functions are already constexpr (e.g. tuple constructors,
get(), tuple_cat(), make_tuple()). 

I think more of them can be made constexpr, in particular tie() and the
comparison operators (operator< and friends).
