Ok, so first step can be support passing blessed objects with 
as_mime_string() method into $email->header_str_set(). Object's 
as_mime_string() will be responsible for producing correct MIME-encoded 
header value

Next, I believe we agreed on $email->header_as_obj($name, $class) method 
which will return object for header name of class. It can use e.g. 
$class->from_mime_string() method for creating object. (Plus there will 
be some registration mechanism to predefine $name => $class mapping, so 
$class argument does not needs to be mandatory).

I think these two parts should be enough for Email::MIME API from user 
of Email::MIME perspective.

And I would propose new module (e.g. Email::MIME::Header::AddressList) 
which will be in Email::MIME distribution and will represent list of 
Email::Address::XS objects with own implementation of ->as_mime_string() 
and ->from_mime_string() methods. That could be used for passing 
list/groups of Email::Address::XS objects into Email::MIME and also get 
them via header_as_obj() API.

$class->from_mime_string() will take raw MIME encoded string and returns 
new object of $class (which will have decoded string parts)
$object->as_mime_string() will convert (Unicode) $object into raw MIME 
encoded string

It is OK for you?
