If you can use unique names for you LOOPs ...

yes, i actually can (but in this early stage i might redesign the whole thing...). but that's a nice idea. then i don't need to query() the template just need to query the template once.

If your LOOPs are not huge then

that's something i don't know. the code should be good for any kind of data. but that might be a good candidate for an option like use MyModule qw(auto_reverse) or something.
