An improved version of ``std::tie``
-----------------------------------
`std::tie()`_ does not work well with :doc:`sol::function<function>`'s ``sol::function_result`` returns. Use ``sol::tie`` instead. Because they're both named `tie`, you'll need to be explicit when you use Sol's by naming it with the namespace (``sol::tie``), even with a ``using namespace sol;``. Here's an example:
.. code-block:: cpp
sol::state lua;
lua.open_libraries(sol::lib::base);
const auto& code = R"(
function test()
return 1, 2, 3
end
)";
lua.script(code);
int a, b, c;
//std::tie(a, b, c) = lua["test"]();
// will error: use the line below
sol::tie(a, b, c) = lua["test"]();
