I recently decided it was time to upgrade my Windows 64-bit version of ActivePerl from 5.10.1.1007 to 5.22.2.2203. I'm now getting a new error message when I try to "use" the collection of generally useful subroutines I keep in Plx.pm: 
E:\!!!dh()testplx
Can't use 'defined(@array)' (Maybe you should just omit the defined()?
+) at (#2) line 2842.
Compilation failed in require at C:\!dh\DH\COM\SRC\testplx.pl line 4.
BEGIN failed--compilation aborted at C:\!dh\DH\COM\SRC\testplx.pl line
+ 4.

[download]
This is testplx.pl in its entirety: 
use Carp;
$SIG{__WARN__} = \&carp;
$SIG{__DIE__} = \&confess;
use Plx;

[download]

Line 2842 of Plx.pm is: my ($err_num, $err_txt);

There are 101 occurences of the string "defined" in 98 lines of Plx.pm.

1) Why isn't Carp identifying the correct line?

2) Besides going through 101 occurences, how can I find where (and WHAT) this error really is?

Thanks, everybody!
