From a programmer's perspective, nothing has changed. It means you can't rely on the order in which the keys of a hash a returned by keys (except the documented exception).
If the few of p5p are to make changes that can break the code of the many perl users, even if those breakages come as a result of dependence -- accidental or otherwise -- upon long-term actual -- if undocumented -- behaviour, is it unreasonable to ask that the reasoning behind the change that causes that breakage be publicly known?
With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
