Your response answered my question as posed. Upon further reflection, I realized that what I really want is to prevent my module from making additions to INC in the first place. Is there a way to do that? Basically what I want to find out is the contents of the INC hash from a script that uses my module (but my module's dependencies should not be included in that data, unless those dependencies were used elsewhere in the program). Perhaps I could delete those particular additions to INC in an END block?
