What are good alternatives to qr// precompiled regex, and how do they compare?

Alternatives to Perl's `qr//` precompiled regex include string manipulation methods, simpler regex matching with `m//`, and using regular expression modules like `Regexp::Common`. Each alternative has its use cases, where methods may be more readable or performant depending on the context.

        # Example using m// instead of qr//
        my $string = "Hello World!";
        if ($string =~ /World/) {
            print "Match found!";
        }
