If the becomes a hash, the index size will jump to 40 bytes each. Lua is "smart" and will allocate at the 16 byte rate as much as it can. If the int sequence is broken, the new values will allocate at the 40 byte rate. WebLua has no arrays, only tables. Anyway, the easiest way for numerical indexes is the # operator.
