Well, there is no string.concat :). [I know you meant table.concat.]
Off-topic: wouldn't it be nice if we had a string.concat that just did
(without some sanity checks and maybe luaL_tostring):
int string_concat (lua_State *L)
{
lua_concat(L, lua_gettop(L));
return 1;
}
Sure would make it easier to concat a dynamic number of strings
without using an intermediate table.
