Maybe I am having a problem with English here (in particular in our
use of "over"); it should be quite clear that the "equivalent over
lua_Integer" of luaL_optint is luaL_optinteger (the same function but
over lua_Integers, instead of over ints). And these functions were
not introduced now; luaL_optlong (and others) was always just a macro:
#define luaL_optlong(L,n,d) ((long)luaL_optinteger(L, (n), (d)))
