--- Comment #1 from Collin Reeser <collin.ree...@gmail.com> ---
I was actually burned by this today. Coinciding with the release of 2.068
(though I didn't initially know the release was upon us!), Travis builds for my
project started inexplicably failing. The root cause was that a
setSymmetricDifference call, which had been working for many months, was
suddenly giving nonsense results.
One of the inputs to the call was a .keys() on an associative array.
Presumably, it just-so-happened that the .keys() was yielding sorted output,
but with the change to the internals of the associative arrays this release, it
just-so-happened that the .keys() result wasn't sorted! Since I misunderstood
the documentation of setSymmetricDifference to mean "is-sortable-by 'less'",
and not "must have been, prior to input, sorted by 'less'", I didn't initially
put the .sort() call after the .keys() call.
Too bad so sad. Figured it out, but lost some time to it.
