Your solution looks ok in my eyes. What's the problem? Adding enums is just another if statement ( Update: when you want to implement them as described and not as a regex like qr{\A(?:red|green)\z}xms). For more exotic types just override the mutator, like the email example in the documentation:
# Only accept addresses which look valid.
sub email {
my($self) = shift;
my($email) = @_;
if( @_ ) { # Setting
require Email::Valid;
unless( Email::Valid->address($email) ) {
carp("$email doesn’t look like a valid address.");
return;
}
}
return $self->SUPER::email(@_);
}
I think if you are happy with Class::Accessor, use it. I don't think you would save much lines of code with any other module.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
