A commit somewhere between 5.31.0 and 
84ab3b690861c92bea535c991537bdde20c93750 has broken a test in the test 
suite for CPAN distribution PPI. The range is suggested by this 
cpantesters matrix page:

http://matrix.cpantesters.org/?dist=PPI;perl=5.31.1;reports=1http://matrix.cpantesters.org/?dist=PPI;perl=5.31.1;reports=1

The failures look like this:

#####
t/07_token.t                   (Wstat: 512 Tests: 588 Failed: 2)
   Failed tests:  343, 383
   Non-zero exit status: 2


ok 342 - '0b' not ::Exp
not ok 343 - literal('0b'), syntax error at (eval 322) line 1, near "0b
# "
#
ok 344 - '0b0' is a single token

ok 382 - '0x' not ::Exp
not ok 383 - literal('0x'), syntax error at (eval 353) line 1, at EOF
#
ok 384 - '0x0' is a single token
#####

I haven't managed to bisect this yet, but since PPI has many, many 
dependencies, this is going to cause a lot of installation failures when 
we start to test the CPAN-river-3000 against perl-5.31.1 later this week.

The perl_V attachment is not directly relevant to this report.

Thank you very much.
