Created April 24, 2012 17:18 — forked from stevedonovan/safe_array.lua
This defines an array with strict bounds checking. It is also impossible to set any existing index to a nil value, so the array remains free of holes. The table functions will not work on such arrays because they are userdata, giving an extra layer of pro
