The real problem seems to be that patch 27512 breaks more than it fixes.  I
believe the patch itself is bugged; the brute force search seems to be
triggering in cases where it doesn't seem to be necessary.

I have a project internal to my employer that makes heavy use of the DateTime
module, which was significantly affected by this patch.  DateTime does overload
but not reblessing, but the search is still triggered (for no apparent reason)
whenever the ->clone method is called, even though there's no reason for it (a
completely new reference is created by ->clone, it does *not* rebless anything).

DBIx::Class is also bitten by this; see

Personally I think this patch needs more testing from upstream before it goes
into a stable line update to Fedora.
