Using a luaL_Buffer while traversing a table

[Ignacio Burgueño <ignaciob@...>]

Hi. Does anyone have some tips (or code, preferable :D) on how to 
traverse a table using lua_next while adding stuff to a luaL_Buffer ?
The fact that the buffer operations may change my stack top is giving me 
trouble. I thought of saving the positions of the key and value after 
lua_next, adding stuff to the buffer and then lua_remove(L, value_pos) 
and bringing the key to the top of the stack. I haven't tried this, but 
I'm afraid that it might break the buffer operations.

Regards,
