I've a class (blessed, of course :)) that has variables like:

$self->a = "1";
$self->b = "2";
$self->c = [ '1', '2', '3', '4' ];
I think/hope you meant:

$self->{a} = '1';            # any reason we're quoting integers?
$self->{b} = '2';
$self->{c} = [ qw(1 2 3 4) ];
Now, I want to write a foreach loop to iterate through $self->c and 
print
the values. However:

foreach my $foo ( $self->c ) {
        print $foo;
}
for my $foo ( @{ $self->{c} } ) {
        print $foo;
}
Hope that helps.
