( #3333=superdoc: print w/ replies, xml ) Need Help??

Thank you both. I've found the relevant sections now in perlsub and in the Camel book. For the record, it was as easy as:

sub each_item (&@) { my $test = shift ; foreach ( @_ ) { return 0 unless ( eval &$test ) } return 1 ; }

Thanks again.

Update: On reading kvale's node a little closer, I tried changing my code to:

sub each_item (&@) { my $test = shift ; foreach ( @_ ) { return 0 unless &{$test} } return 1 ; }

...which also worked. Is there any advantage/disadvantage to this over eval?
