in thread Using 'each' to get random (key, value) pair from hash returns "uninitialized value"
An excellent piece of detective work :-)
So just grabbing the key alone and pulling the value manually will work.
knoppix@Microknoppix:~$ perl -Mstrict -wE ' my %hash = ( one => q{ein}, two => q{zwei}, six => q{sechs}, ); say qq{@{ [ %hash ] }}; for ( 1 .. 9 ) { my $k = each %hash || each %hash; say qq{$_: $k => $hash{ $k }}; }' six sechs one ein two zwei 1: six => sechs 2: one => ein 3: two => zwei 4: six => sechs 5: one => ein 6: two => zwei 7: six => sechs 8: one => ein 9: two => zwei knoppix@Microknoppix:~$
Thanks for clearing up the mystery.
Update: Apologies to duelafn, I didn't see his post before making this essentially identical reply.
Cheers,
