version 0.011; 2017-07-15
* update test suite to not rely on . in @INC, which is no longer
necessarily there from Perl 5.25.7
* no longer include a Makefile.PL in the distribution
* update op-munging code to the PERL_OP_PARENT-compatible style
(though none of it is actually used on Perls new enough to support
PERL_OP_PARENT)
* rename internal gen_*_op() functions into a better style
* consistently use THX_ prefix on internal function names
