* Package name : libhash-safekeys-perl Version : 0.04 Upstream Author : Marty O'Brien <m...@cpan.org> * URL : https://metacpan.org/release/Hash-SafeKeys * License : Artistic or GPL-1+ Programming Lang: Perl Description : get hash contents without resetting each iterator Every hash variable in Perl has its own internal iterator, accessed by the builtin each, keys, and values functions. The iterator is also implicitly used whenever the hash is evaluated in list context. The iterator is "reset" whenever keys or values is called on a hash, including the implicit calls when the hash is evaluated in list context. That makes it dangerous to do certain hash operations inside a while ... each loop: while (my($k,$v) = each %hash) { @k = sort keys %hash; # Infinite loop! @v = grep { /foo/ }, values %hash; # Ack! print join ' ', %hash; # Run away! } The package will be maintained under the umbrella of the Debian Perl Group. -- Generated with the help of dpt-gen-itp(1) from pkg-perl-tools.
