More (although not as neat):

my $one = !$|; my $one = cos; # Given that $_ == 0. my $one = cos $|; my $one = cos atan2 $|, cos; my $one = sin atan2 sin, $|; my $one = length $/; # Note: possibly 2 under Windows or DOS. my $one = length $"; my $one = length $;; my $one = length $^L; my $one = $^T/$^T; my $one = @ARGV >= 0; my $one = grep //, ($_); my $one = !undef; # Note: the following may be Unix-only. Will not work if run as root, # as root's UID and GID are (always?) zero. my $one = $</$<; # User ID. my $one = $>/$>; # Effective user ID. my $one = $(/$(; # (Space-separated list of) group ID(s). my $one = $)/$); # (Space-separated list of) effective group ID(s +).

Ways to get 2:

my $two = length $:; my $two = $^F; # Note: system-dependent.
