In my case, removing -1 in this part of code:

template <class T, class F, class... Ts, class ExclusionType>
struct member_function_arity_excluding<T, F, std::tuple<Ts...>, ExclusionType, std::enable_if_t<is_proxy_member_function_v<T, F>>>
    : std::integral_constant<std::size_t, (0 + ... + (std::is_same_v<std::decay_t<Ts>, ExclusionType> ? 0 : 1)) - 1>
{
};

To:

template <class T, class F, class... Ts, class ExclusionType>
struct member_function_arity_excluding<T, F, std::tuple<Ts...>, ExclusionType, std::enable_if_t<is_proxy_member_function_v<T, F>>>
    : std::integral_constant<std::size_t, (0 + ... + (std::is_same_v<std::decay_t<Ts>, ExclusionType> ? 0 : 1))>
{
};

It works!
But can break another part of code that I have not tested yet.

Is this a class function or global function ?

Should be fixed in 36c8f88

Could you verify it's ok on your end as well ? Added a unit test in the commit, would be nice if you can check if this is equal to your use case.

Btw now you can do:

luabridge::getGlobalNamespace(L)
    ...
    .addFunction("__mul",
        luabridge::overload<const Vector3&>(&Vector3::operator*),
        luabridge::overload<float>(&Vector3::operator*))
    ...
    .endClass();

for even simpler overload resolution

It is working now.
Thanks!
