    core/tuple-automaton: declare `indices` at namespace scope · dc90ec99
    Paul Hervot authored
    In C++14, static constexpr expressions that are odr-used must be
    declared in the compilation unit at namespace scope even if they are
    defined and assigned to in the class.
    
    The `indices` static constexpr attribute of tuple_automaton_impl was
    missing that namespace-level declaration, some compiler were fine with
    it, but clang 8 isn't, unless compiling with -O1 or higher.
    
    Fix #216
