This is less than ideal, but it gives you a little better visibility than just line number.
{ my ($line,$occurrence) = (0,0);
sub some_sub {
$, = ' - ';
my @caller = caller();
if($caller[2] == $line) {
$occurrence++;
}
else {
$line = $caller[2];
$occurrence = 0;
}
print @caller, $occurrence, $/;
}
}
You example shows the biggest limitation to this approach.
$occurrence will just keep growing since it is the same line number. But if you know you are dealing with a specific number of calls on the line, you can mod whatever and get the specific occurence on the line.
