Hi,
Somehow I can't seem to do these announcements without an error :(

Wrong attribution. The patch was by Yue Wang, sorry.
Never mind:)

btw, vpack() and hpack() still admit numeric third argument (exactly
and additional are just macros in WEB source). So maybe it will be
better to change

            else if (lua_type(L, 3) == LUA_TNUMBER) {
                m = lua_tonumber(L, 3);
            } else {
                lua_pushstring(L, "incorrect 3rd argument");
            }

to

            else {
                lua_pushstring(L, "incorrect third argument");
                lua_error(L);
            }

So the conditional tests will be more strict.

Anyway, since the API will be changed in the future (as Hans said in
that mail), It is fine if we don't touch that at this moment.
