You're quite right - I'd always assumed that's why they use the convoluted concat method without ever actually checking that table.concat honours __concat.As table.concat does not accept things with __concat metamethods, they do not need to be considered. Likewise, numbers need no special treatment as lua_isstring / lua_tolstring automatically convert numbers to strings.
Now I too, am left scratching my head ;).- Alex
