Alvaro Herrera 7de38741c0 Remove usage of &PL_sv_undef in hashes and arrays ... According to perlguts, &PL_sv_undef is not the right thing to use in those cases because it doesn't behave the same way as an undef value via Perl code. Seems the intuitive way to deal with undef values is subtly enough broken that it's hard to notice when misused. The broken uses got inadvertently introduced in commit 87bb2ade2c by Alexey Klyukin, Alex Hunsaker and myself on 2011-02-17; no backpatch is necessary. Per testing report from Greg Mullane.
