I would have thought of creating a function which went through the
list before the eval() usage in OP. In any case, and operation could
have been easily implenented something like ...
# Adjust truth value tests & returned truth values as you like.
sub short_circuit_list_and
{ my @list = @_;
return unless scalar @list;
my $and = 1;
foreach my $i (@list)
{
return 0 unless $i;
$and = $and && $i ? 1 : 0;
}
return $and;
}
Am i seriously missing something?
UPDATE: I could not settle w/ the ternary operator inside the
loop, so a variation ...
# Adjust truth value tests & returns as you like.
sub list_and
{ my @list = @_;
return unless scalar @list;
my $and = 1;
foreach my $i (@list)
{
return 0 unless $i;
$and &&= $i;
}
return $and ? 1 :0;
}
