I didn't realise that LUA_NOCVTN2S disabled the lua_tolstring automatic conversions (I thought it controlled just the Lua-side ones like "a"..1). Now that I look, it does indeed. I've learnt something today!

Now I'm really kicking myself for not enabling those in my last project, maybe I can quietly sneak them in with enough testing of all the existing code... (I was trying to be as close to stock Lua as possible, at the time, but it has progressed to the point where I probably could safely change this).

Cheers,
