I had a look in the manual this is why I'm asking if there is another
common solution! :O)

>>I've got a simple question.
I'm storing into a table several items(other tables) using a numerical
index as key and I would like to know how many elements are into the
table.So I tryed with lua_getn(); The problem is that I'm not inserting
sorted elements, for instance if I insert the first element with key 8
getn() will return 8. Is there any way to have the real number of "non
nil" elements?
Write your own! :o)
getn returns the highest numerical key. Have a look in the manual.
