Although it is correct to use lua_pushvalue(L, LUA_GLOBALSINDEX) to
push the global environment on the stack, you do not need this to
traverse it. As already answered, you can use LUA_GLOBALSINDEX as an
index in any call that asks for an object. So you can call
lua_next(L, LUA_GLOBALSINDEX) directly.
