Compare perl -mstrict -we 'my $v;for(1..3) { print "$v\n";$v++; }' with perl -mstrict -we 'my $v = "";for(1..3) { print "$v\n";$v++; }'
Hmm, I could swear I read in my manual that perl will automatically initialize variables. But, that's obviously not case, as your example demonstrates.
Thanks for the info!
No problem :)
