You pretty much had it right before... 
   #open(FILE, my $aref); #or die "Cannot open: $file\n";

except your my $aref in the open is overriding the
my ($aref} = @_;
at the head of your subroutine, so aref in the open is undef... do 
open(FILE, $aref) or die "Cannot open: $file\n"; 
$line = <FILE>;

[download]
and you should be golden

<> works on @ARGV, not @_... if there is nothig it @ARGV it will read from STDIN

Update oh yes, the while loop would also use <FILE> instead of <>
