Bug #108203 for lexical-underscore: Can't use global $

Fri Oct 30 11:56:10 2015 SREZIC [...] cpan.org - Ticket created

Subject:

Can't use global $_ in "my"

Test suite fails with perl 5.23.4: Output from '/usr/bin/make test': PERL_DL_NONLAZY=1 "/bbbike/perl-5.23.4/bin/perl5.23.4" "-MExtUtils::Command::MM" "-MTest::Harness" "-e" "undef *Test::Harness::Switches; test_harness(0, 'blib/lib', 'blib/arch')" t/*.t Can't use global $_ in "my" at t/01basic.t line 12, near "my $_ " Can't use global $_ in "my" at t/01basic.t line 23, near "my $_ " Can't use global $_ in "my" at t/01basic.t line 28, near "my $_ " Execution of t/01basic.t aborted due to compilation errors. # Looks like your test exited with 255 before it could output anything. t/01basic.t ..... Dubious, test returned 255 (wstat 65280, 0xff00) Failed 6/6 subtests Probably due to this change, mentioned in perl5.23.4's perldelta.pod: Lexical $_ has been removed "my $_" was introduced in Perl 5.10, and subsequently caused much confusion with no obvious solution. In Perl 5.18.0, it was made experimental on the theory that it would either be removed or redesigned in a less confusing (but backward-incompatible) way. Over the following years, no alternatives were proposed. The feature has now been removed and will fail to compile.

A possible patch (make 5.23.4 and later behave like 5.8.9 and earlier) can be found at: http://cpan.cpantesters.org/authors/id/S/SR/SREZIC/patches/lexical-underscore-0.003-RT108203.patch
