The problem with while (my $line = <DATA>) {} is real, it's just obscure
ARRRRGH! :-)
As has already been pointed out this hasn't been a problem for some time. Perl automatically adds the defined for you, as you can easily see by running:
a% perl -MO=Deparse -e 'while (my $line = <DATA>) {}' while (defined(my $line = <DATA>)) { (); } __DATA__ -e syntax OK
This hasn't been a problem for Perl for quite some time, and I wish people wouldn't keep saying it is ;-)
