takeda at takeda.tk has reassigned Bugzilla Automation <bugzilla at FreeBSD.org>'s
request for maintainer-feedback to perl at FreeBSD.org:
Bug 214617: mail/p5-Mail-Alias: library no longer works on perl5.24
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=214617



--- Description ---
With perl5.20 the perl was issuing a warning but continued to work, after
upgrade to 5.24 the warning changed into an error that looks like this:

Can't use 'defined(@array)' (Maybe you should just omit the defined()?) at
/usr/local/lib/perl5/site_perl/Mail/Alias.pm line 85.
Compilation failed in require at ./bogofilter-milter.pl line 335.
BEGIN failed--compilation aborted at ./bogofilter-milter.pl line 335.

I'm not too familiar with perl but changing:

 croak "Unknown format '$fmt'"
  unless defined @{$pkg . "::ISA"};

into:

 croak "Unknown format '$fmt'"
  unless defined $pkg . "::ISA";

Seems to solve the issue for me.
