Subject: | Minimum perl version 5.10.0? |
I found this in lib/Data/PrefixMerge.pm:
355 my ($self, $data, $maxdepth, $_mem, $_curlevel) = @_;
356 # $_mem is to handle circular reference
357 $maxdepth //= -1;
358 $_curlevel //= 1;
359
The defined-or operator was introduced in perl 5.10.0. If you want to
use this construct, please make it clear in the Makefile.PL so that your
users get informed before the tests fail. This page has suggestions how
to proceed:
