If modifying the content is something you often do, it would be kind of cool to have the set method take a block of code and act internally: 
$self->content(sub{s/foo/bar/g});

where the content method would recognize the code ref and treat the current value as $_ within it. Something vaguely like: 
sub content {
    my $self = shift;
    if (@_) {
        my $set = shift;
        if (isa($set,"CODE")) {
            # fixed :-)
            &$set for $self->{'content'}; # Code to modify content (as
+ $_) gets executed
        }
        else {
            $self->{'content'} = $set;   # Direct set
        }
    }
    $self->{'content'};
}

Another spiffy (but experimental) technique would be to make the content method an lvalue subroutine. So you could write the one-liner 
$self->content =~ s/foo/bar/g;
# instead of
# $self->content(map { s/foo/bar/g } map $_, $self->content);

We're not really tightening our belts, it just feels that way because we're getting fatter.
