No, not entirely.  The copy could decide to make a deep copy of the
whole message: there is a need for a second instance.  The move can
reside to only a re-administration.  Like cp and mv on UNIX: cp is
slow and mv is fast.

I see that the autoloading in IMAP4::Head is missing.  This means that I
need some time to send you a (probably large) fix.  Hopefully today.

That is because the IMAP protocol can provide some of the header lines
via a separate path.  They are kept in that ::Head object.  In my first
investigation, I suspect it should be derived from
Mail::Message::Head::Subset, not Mail::Message::Head.  It's quite some
time since I last had a look at this code...

Probably.  As you can see in de manpage, it says: 'under development'
for Mail::Box::IMAP4.  Mainly because I didn't get enough feedback on
the code.  That doesn't mean that I do not intend to make it to work
perfectly, but I cannot do that alone for folder types which require
external servers... mbox/maildir/mh are much easier to get right.
So I hope you can help me to get a step ahead.
