hello again dear monks it seems i have stumbled again on not knowing how to use switch statement properly. ok,so in response to these questions ive asked,i thank very much the people who answered me there http://perlmonks.org/?node_id=621046 http://perlmonks.org/?node_id=621054 http://perlmonks.org/?node_id=621013 and i have finally got a solution here it is: 

use strict;
use Switch;
my $text="bla fred wilma fuck fred fuck wilma bla fred fredfred";
$text =~ s{(fred|wilma)}
    {
        my $replace_text;
        if($1 eq "fred") {
            $replace_text='wilma';
        }
        else {
            $replace_text='fred';
        };
        $replace_text;

    }eg;
print $text;

however to make the code i write more elegant i want to use switch instead of the if's statement but my code doesnt want to work. ive read perl documentation for switch already, no luck. 

use strict;
use Switch;
my $text="bla fred wilma fuck fred fuck wilma bla fred fredfred";


$text =~ s{(fred|wilma)}
    {
        my $replace_text;
        switch($1) {
            case 'fred' {$replace_text='wilma'}
            case 'wilma' {$replace_text='fred'}
        };
        $replace_text;

    }eg;
print $text;
