Hello wisiest ones! for first time in my 'career' I considering to modify $SIG{__WARN__}.

Until now I have considered this like something of Magic an Power never disclosed to other then Perl fellows.. so I never played with it in a reverencial ignorance (I suspect also that a BAD or Buggy signal handler is dangerous like a mad dog).

Now, when the ChatterBox is empty like my bank-account, I'm write a little module in which I wont to use Carp's cluck and confess facility and I want to log succes and failure so my first approach in the caller script was: 
 use MyLittlePlace::BrandNewMod qw(a b c);
 
 close STDERR;
 open(STDERR, ">&STDOUT") || die " uh uh ?! we mad ?! ";
 
 $|++;

so that I can log to a file all the return output with useful information and in the right order..

Then the 'UcanDObetter' devil told me 'you dont want a dayly spam mail full of OK report, true? invent some kind of trigger that fire an advise on more then zero errors..'.

Mmh.. I have SuperSearched this and I replaced the above code in this way in the caller script: 
 close STDERR;
 # no more redirect of handler 
 # open(STDERR, ">&STDOUT") || die " uh uh ?! we mad ?! ";
 $|++;
 
 my $err_count = 0;

 $SIG{__WARN__} = sub { ++$err_count;print STDOUT @_ };
 $SIG{__DIE__} = sub  { ++$err_count;print STDOUT @_ };

 #do all the stuff and at the end..
 &advise_me($content) if $err_count > =;
 print $err_count,
       " ERROR",($err_count eq 1 ? '' : 'S' ),
       " IN $0\n";

Is a Rigth thing to do in my case? is better do it in the module in some way ? it is dangerous? it make sense?

thks in advance
