These things can be found out by experimentation. Experimentation is easy and highly encouraged.

c:\@Work\Perl\monks>perl -wMstrict -le
"use Data::Dump qw(dd);
 ;;
 my $value;
 ;;
 my $alice = 'alice';
 my $bob   = 'alice';
 ;;
 $value = $alice eq $bob;
 dd 'result of evaluating a comparison that is true', $value;
 ;;
 $alice = 'alice';
 $bob   = 'bob';
 ;;
 $value = $alice eq $bob;
 dd 'result of evaluating a comparison that is false', $value;
"
("result of evaluating a comparison that is true", 1)

("result of evaluating a comparison that is false", "")
