Actually, the list of coderefs does not use symbolic references. Using symbolic references would be something like&{"$recovery};. What I do is use hard references instead.

And, as always, you should comment any use of an advanced feature, such as coderefs, if you expect your code to be maintained by people who know less than you do. This is for every language, not just Perl.

Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.
