[Petal] While loops

[Mark Holland]

Hi,

I'm not sure if the following is at all possible -I'm trying to write a 
while loop in petal using a database cursor.

In perl it would be something like this:

while (my $obj = $cursor->next) {
    print $obj->some_value();
}

But in petal...? I've tried everything and can't get anything work.

I know that I could read all the objects into an array and then just 
pass that and loop through it, but if I can save myself the extra step 
and make my code neater I would like to.

Any ideas? Am I missing something very basic for which I will be made to 
feel stupid? ;-)

Cheers,
Mark
