in reply to In-place sort with order assignment

You can use Sort::External for stuff like this.
use Sort::External; my $sortex = Sort::External->new; while ( my ($k, $v) = each %hash) ) { # aliases, so no memory hit $sortex->feed($k); } $sortex->finish; my $counter = 1; while (defined($_ = $sortex->fetch)) { $hash{$_} = $counter++; }
