Why is there no converting function available in Net::LDAPto deal with GUID values from AD?

Hi,

I'm using Net::LDAP to read information from
a Microsoft Windows AD-Server by LDAP.

On of the attributes is the "objectGUID", a binary value
that's often used in AD context.
<http://msdn.microsoft.com/de-de/library/windows/desktop/ms679021%28v=vs.85%29.aspx>

Google has shown me solutions how I can work
with this "objectGUID", for example 
<http://www.perlmonks.org/?node_id=897883>.

But why is there no converting "helper-function" available in
Net::LDAP to deal with GUID values from AD?

Best Regards,
Achim
