That's what we read in perl5110delta:
The key change here is that \d will no longer match every digit in the + unicode standard (there are thousands) nor will \w match every word +character in the standard, instead they will match precisely their PO +SIX or Perl definition.
AFAIU, that means \w will no more match non-ascii letters in Unicode strings. I have just built a fresh 5.11 and I don't witness this change:
Now on to 5.11:% perl -v # my system perl This is perl, v5.10.0 built for i486-linux-gnu-thread-multi % perl -E '"\x{432}" =~ /\w/ and say "matched"' # cyrillic letter v matched
% ~/work/perl-5.11.0/perl -v This is perl, v5.11.0 (*) built for i686-linux ... % ~/work/perl-5.11.0/perl -I lib -CS -E '"\x{432}" =~ /\w/ and say "ma +tched"' matched
On one hand, this is quite a relief as it means I don't have a lot of very broken code on me. On the other hand, this contradicts my understanding of the declared change.
Can someone enlighten me?
