"library" instead of "core". Please disregard/delete/void #36532.
My apologies. ]
Subs defined with the lvalue attribute are unrecognized or mishandled
when running inside the Perl debugger. For example the following
script runs fine on the command line but fails in the debugger.
# test_script.pl
use strict;
use warnings;
my $var = 0;
sub foo : lvalue {
$var;
}
foo = 1;
die "\$var unchanged ($var)" unless $var; # fails in debugger
print "OK: $var\n";
__END__
% perl test_script.pl
OK: 1
% perl -d test_script.pl
Loading DB routines from perl5db.pl version 1.28
Editor support available.
Enter h or `h h' for help, or `man perldebug' for more help.
main::(test_script.pl:4): my $var = 0;
main::(test_script.pl:5): sub foo : lvalue {
DB<1> c
$var unchanged (0)

Debugged program terminated. Use q to quit or R to restart,
use O inhibit_exit to avoid stopping after program termination,
h q, h R or h O to get additional info.
