Hey all,

On Windows (2012 server, running perl 5.22.1), I get expected results using use if ...;:

use if $^O !~ /MSWin/, "Proc::Daemon";
use if $^O =~ /MSWin/, "Win32::Daemon";

print "$INC{'Win32/Daemon.pm'}\n";
exit;

__END__
C:/berrybrew/5.22.1_64/perl/vendor/lib/Win32/Daemon.pm

But on Ubuntu, running v5.22.1:

use if $^O !~ /MSWin/, 'Proc::Daemon';
use if $^O =~ /MSWin/, 'Win32::Daemon';

print "$INC{'Proc/Daemon.pm'}\n";
exit;

__END__
Too few arguments to 'use if' (some code returning an empty list in li
+st context?) at /home/ubuntu/perl5/perlbrew/perls/perl-5.22.1/lib/5.2
+2.1/if.pm line 7.
BEGIN failed--compilation aborted at /home/ubuntu/perl5/perlbrew/perls
+/perl-5.22.1/bin/bbtester line 6.

I can't really find anything about this being a known problem. Proc::Daemon is properly installed (as I can use it in a module without the conditional use):

perl -MProc::Daemon -E 'say $Proc::Daemon::VERSION'
0.23

Can anyone spot anything I'm doing wrong, or is this something that just doesn't work reliably?

Update: I just realized that this was my 1,000th post here on PerlMonks :)
