Hello everyone, In effort to get a fix out before Perl 6 goes mainstream, Barry and I have decided to pronounce on what we want for our stable releases. What we have decided is that 1. Simple hash randomization is the way to go. We think this has the best chance of actually fixing the problem while being fairly straightforward such that we're comfortable putting it in a stable release. 2. It will be off by default in stable releases and enabled by an envar at runtime. This will prevent code breakage from dictionary order changing as well as people depending on the hash stability.

Okay, good call!
