I was just wondering why the aux library provides luaL_opt* functions
for integers, numbers and strings but not for booleans. It is not a big
deal since I just define my own as
	int luaL_optboolean (lua_State *L, int narg, int def) 
		return lua_isboolean(L, narg) ? lua_toboolean(L, narg) :

I am just curious about why some types were chosen for the opt functions
and some were not.
