from the camel book: "Use of defined on aggregates (hashes and arrays) is
deprecated."
so, change
if (!defined @fields)
to
unless (@fields)
and not only be idiomatic, but exhibit the behavior you want :)
but seriously, it's a perl thing, not a mod_perl thing:
#!/usr/bin/perl
sub test {
my @array;
if (!defined @array) {
print "not defined\n";
} else {
print "defined\n";
}
push @array, "item";
}
test();
test();
results:
not defined
defined
