Up to now, if you passed a "tied" object to a PL/Perl operation, it would most likely get treated as "undef", since we failed to perform get magic on values we're passed. Tied hashes worked partially, in that you could read out their keys, but the values always read as undef. To fix, use hv_iterval() not HeVAL() to fetch values from perl hashes, and be careful to apply plperl_materialize_sv() before testing SvOK() or SvROK() on any perl SV. Add regression test cases exercising some typical usage scenarios for tied objects. Arguably this is a bug fix, but in view of the lack of field complaints to date, let's treat it as a new feature instead. The risk/reward ratio for back-patching isn't attractive.
