Because you have overloaded "" for objects of class Foo.

Not really. Here's an example:

Hi ALL,
I know i am missing something somewhere:
perl -e '
package Foo;
use overload q("") => sub {return shift->{bar}};
$s = bless{bar=>"hello"}, Foo;
print "$s\n"
'
prints "hello".
Whereas:

I've never seen grep used with [ ] brackets before - it

Hello,
I can't use a method called edges($u, $v) in the Graph::Base package. It will
use an internal method _edges defined in Graph::Directed package. Even I copy
this _edges() from Directed package to the Base package, I still can't use it,
The program freezed when I use '@e = $G->edges;'. I

Sorry, didn't think it through (before anybody notices.). Remove the
thing that executes the script (the bit in backticks) and just have the
process start on a cron job.
Tired, apologies.

Hi,
you could write a handler for the signal alarm that starts a new process and
kills the current:
$SIG{ALRM} = {
`this-script`;
exit;
};
At the beginning of the script set the alarm to go off 24 hours later:
alarm(84600);

Why do you need to kill and restart it? Can't you just print the date at

There is an errmode() and dump_log(). Maybe that is what you are trying to
capture.

You basically look at the advantages and disadvantages of different

I need to print them into the same file and I'm doing this.

I would like to shorten it to
