As a workaround, I always add the following to my hash of template vars:
'as_list' => sub { return ref($_[0]) eq 'ARRAY' ? shift : [ shift ] }
Then I can do this in the template:
[%
FOR i = as_list( form.field('time_zone').options );
"value = $i.value, lable = $i.label\n" | stderr;
END;
%]
I had wanted to do this as a vmethod, but I needed it to work for lists
of objects, too, so a global function was the best I could come up with.
I guess this could be rolled into a plugin or something...
