I think I have a great new revolutionary way of writing API bindings. I'll polish things up and try to rewrite a few manual bindings to verify it works, but then it should be a breeze to add new bindings. Possibly even the ToLua++-generated bindings could be rewritten to use the new way.
Basically, you can now do this:

int someBindingFunction(lua_State * a_LuaState)
{
 cLuaState L(a_LuaState);
 int overloadUsed;
 cPlayer * self;
 int paramI1, paramI2, paramI3;
 AString paramS1, paramS2;
 L.ReadParams(overloadUsed,
   std::tie(self, paramI1, paramS1),
   std::tie(self, paramI1, paramI2, paramS1),
   std::tie(self, paramI1, paramS1, paramI2),
   std::tie(self, paramI1, paramI2, paramS1, paramS2, paramI3)
 );  // Reads all params, chooses the right overload, reports any errors if none matches
 switch (overloadUsed)
 {
   case 0:
   {
     // paramI1, paramS1 are valid
     break;
   }
   case 1:
   {
     // paramI1, paramI2, paramS1 are valid
     break;
   }
   case 2:
   {
     // paramI1, paramS1, paramI2 are valid
     break;
   }
   case 3:
   {
     // paramI1, paramI2, paramS1, paramS2, paramI3 are valid
     break;
   }
 }
}
