Re: Hash order randomization is coming, are you ready?

[chrestomanci]

Will the order of keys returned change from one call to the next on the same has in the same run of a script? Is there an explicit shuffle done every time you call keys etc?

Consider the code:

my $hashRef = someFuncCall();

my $keys1 = join(' ', keys %$hashRef);
my $keys2 = join(' ', keys %$hashRef);

print "Key order is not stable" if $keys1 ne $keys2;
