Perception of text

[uksza]

Pious Monks,

I've heard about funny attribute people's perception.
Look at this:
I tnhik you know what I am wintirg to you. But I must rbemeer to keep fsirt and last lteerts on the plcae and do not tucoh sorht wdors.
It's nice, istn't?
So, I try to write function to do it:

sub perception() {
    my @result;
    my @words = split / /, shift @_;

    foreach my $word (@words) {

        if ( length $word < 5 ) {
            push @result, $word;
            next;
        }

        my @toRandomize = split //, $word;
        my $letters = ( ( scalar @toRandomize ) - 1 );
        $letters-- if $word =~ /\W$/;

        for ( my $i = 1 ; $i < $letters ; $i++ ) {
            my $rnd = ( 1 + ( int rand( $letters - 2 ) ) );
            my $temp = $toRandomize[$i];
            $toRandomize[$i]   = $toRandomize[$rnd];
            $toRandomize[$rnd] = $temp;
        }
        push @result, join( '', @toRandomize );
    }
    return join ' ', @result;
}

What are you think about this?
How can I do it better?
And, how to work with words like "your's", "you're" etc.? - " ' " should stay on the place. $letters-- if $word =~ /\W$/;

 if ( $word =~ /\W+/) {
                $letters = (index $word, $&)-1;
        }

Stay in peace and wisdom, monks.

P.S.
Is my code styl good? Not to much "talkative"?

This is not an attribute of perception, it is a figment of an urban legend spam. Please see this article why this is only likely to work in very arbitrary texts, not in texts in general. (and also some tips on other ways to optimize your scrambler :-)

You're absolutely right. I've used this words coz my poor english ability ;-)
