Not at the moment. As it turned out Xref is buggy.

    Yes, at the moment. I don't know why you link to that post because Concise doesn't give a number for the my, and Xref doesn't give a line number for the while.

      > give the same number

      "would give" the same number if Xref was ever fixed.

      edit

      To be clear: line numbers in Perl will never be 100% exact, because statements can span several lines, and because sometimes multiple statements are optimized into a single one.

      But there is no reason (AFAIK) why a variable should be skipped from a report or the declaration being reported after the first use, like Xref is doing now.

        No, without change. When they both give a line number for an op, it matches. The reason is they get they info from exactly the same place.
