Re^2: How to check whether my array contains element x

[MidLifeXis]

You might want to change /^$value$/ to /^\Q$value\E$/, especially if $value may contain re metacharacters, but it depends on the application.

while (<>) {
    chomp;
    print qr(^$_$), "\t", qr(^\Q$_\E$), "\n";
}
__END__
foo
(?-xism:^foo$)  (?-xism:^foo$)
foo[bar]
(?-xism:^foo[bar]$)     (?-xism:^foo\[bar\]$)
