I guess that would not need another module, but the introduction of major changes to Canivore, e.g. one or more of the following

• store variable / line-number pairs passed as arguments to Devel::Carnivore::import() in a package hash for lookup
• use source filtering to insert watch hooks at those lines (before or after that line?) without adding new lines to the file
• check for the line number in STORE whether the line number caller() reports is in the desired range

The above are just some rough ideas I would try to implement, maybe there are other (and better) ways. Have a look at Filter::Util::Call for source filtering and e.g. Spiffy for a usage example.
