Subject: [PATCH] Fix injecting $INC{'constant.pm'}
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Perl 5.32 revealed that "use constant::tiny" injected an undefined
value to $INC{'constant.pm'}.
$ perl -Ilib -e 'use constant::tiny; use constant;'
Attempt to reload constant.pm aborted.
Compilation failed in require at -e line 1.
BEGIN failed--compilation aborted at -e line 1.
That's becaue Perl 5.32 started treat an undef value differently and refuses
reloaded once failed module. A diagnostics explanation:
(F) You tried to load a file with use or require that failed to
compile once already. Perl will not try to compile this file again
unless you delete its entry from %INC. See "require" in perlfunc and
"%INC" in perlvar.
This patch fixes setting the $INC{'constant.pm'} value.
