... I believe the difference is because I made 'composite' an array with
contiguous numerical indexes, with optimized access in Lua 5.1 (direct

more complex tests (hashing the index?) to see if the slot is empty ...

Might be a stupid question, but would the optimization apply even if
the first index was, say, 1296?
