Making this an {} would simplify the code since you can use numbers as keys, and
a request for an item not in the object returns undefined.

 a = {};
 > a = {}
 Object {}
 > a[1] = true
 true
 > a[1] == true
 true
 > a[2] == true
 false

Great idea!  Done.

If you don't switch to using a map, then this should change to 
  != -1. Here and below.

Switched to map.
