"... version number (mumble) of module List::Util ..."

That would be 5.20.0. See http://perldoc.perl.org/5.20.0/List/Util.html.

In 5.18.2, and earlier versions, they appear in SUGGESTED ADDITIONS, along with Perl code to implement them:

sub any { $_ && return 1 for @_; 0 }
sub all { $_ || return 0 for @_; 1 }
sub none { $_ && return 0 for @_; 1 }
sub notall { $_ || return 1 for @_; 0 }
