One micro-benchmark can be found here:

    <http://jsperf.com/array-index-push/3>

In all the more recent browsers except IE9, `push` is faster.
Unfortunately, in IE8 and IE9, it's quite a bit slower.  And since
that's already the slowest environment, you'll have to make a decision
with that in mind.

But regardless of speed, `push` is certainly cleaner.  And in my mind,
that counts for a fair bit.


Thanks Scott --- I'll probably revert to .push
