Boost C++ Libraries: Ticket #3358: return type of functions incorrect

Steven Watanabe — Wed, 19 Aug 2009 22:35:48 GMT

Actually, I think it would be better if fusion::push_back were overloaded to allow either const or non-const arguments, like

    template <typename Sequence, typename T>
    inline typename result_of::push_back<Sequence, T>::type
    push_back(Sequence & seq, T const& x);
    template <typename Sequence, typename T>
    inline typename result_of::push_back<Sequence const, T>::type
    push_back(Sequence const& seq, T const& x);

Regardless, result_of::push_back ought to work correctly for non-const arguments. If push_back always adds const, then so should result_of::push_back.

Fixed by https://github.com/boostorg/fusion/pull/106 .

    push_back(Sequence const& seq, T const& x);

It will be handled in #3954.
