请教一个switch语句的问题

Perl code

 swith($line)    {        case $line=~ m/taxid:9606\(Homo sapiens\)\ttaxid\:9606\(Homo sapiens\)/            {                print M_PROCESSED_human $line;            }        case  $line=~ m/taxid:10090\(Mus musculus\)\ttaxid\:10090\(Mus musculus\)/            {                print M_PROCESSED_mouse $line;            }        else            {                next;            }

难道LZ的编辑器没有语法高亮？
[解决办法]
[code=Perl] use Switch;

switch ($val) {
case 1 { print "number 1 " }
case "a " { print "string a " }
case [1..10,42] { print "number in list " }
case (\@array) { print "number in list " }
case /\w+/ { print "pattern " }
case qr/\w+/ { print "pattern " }
case (\%hash) { print "entry in hash " }
case (\&sub) { print "arg to subroutine " }
else { print "previous case not true " }
}[/code]
