Maintaining the Perl 5 Core: Report for Month 36

No Comments

Dave Mitchell writes:

I spent last month:

  • eliminating the OP_PUSHRE op, converting OP_SPLIT from being a LISTOP to a PMOP, and making split faster - see v5.25.5-71-gdbdb57e;
  • working on various fuzzer tickets;
  • trying to work out when one should use pad_free(), pad_swipe(), S_op_clear_gv() or just plain SvREFCNT_dec(). I gave up on this for now;
  • picking some quick and low-hanging fruit off my TODO list;
