I've just spent the last few days hacking around this. The solution I
came up with (I'll post the patch on tuesday or so) was to make links
always return an array ref (tied to DBIx::Recordset), rather than the
full glob.
Works in most usage cases - if you want the object, you can easily get
it with tied(@$arrayref). It does mean that you have to do
$set->{-key1}[0]{key2} (ie: insert "[0]" between consecutive hash
lookups), which you didn't /have/ to do before.
An alternative may be to patch perl's sv_upgrade to get back the old
globref handling behaviour. Given that a tied hash returning a glob
was always breaking the rules, I'm not sure if such a patch would be
accepted anyway..
