I have done some very unscientific tests: for each kind of list (Array,
old ArrayList, new ArrayList, new ArrayList - using sugar) the test code
creates a million-item array and then increments each value that it
contains.
This is how long each test takes:
Array: 0.1 sec
old ArrayList (get/set Item): 0.8 sec
new ArrayList (get/set Item): 0.9 sec
new ArrayList ([]): 5.6 sec
In summary, indexing sugar is really slow, but get/set item don't seem
to get much slower just by implementing Proxy.

Can you run a some of quick tests? Iterating on 1000 items via for-each
on an Array, via a loop on ArrayList.getItemAt() before your Proxy change
and using [] and for-each on ArrayList after your new Proxy change?
And maybe also try 5000 and 10000 items if you have time.
