in thread Inspecting the name of a variable


I found Data::Dumper::Names with this thread . In this manual of Data::Dumper::Names, there is "Unknown Variables" section.

"Unknown Variables" section seems to me having some relation with your case... not printing name "$x".

Sorry if I am looking into wrong direction.

    Thats where I started, but if you look into Ovid's code you will see that he's only inspecting lexical variables.

      I saw it. It used the same module, PadWalker.

      With -d debug, when I type V at for loop, I see "$x = 42" in the list. It seems there is some way for printing variable names...

      I know nothing for perlguts,and don't understand what is Alias here ...
      Hope you get some hints from superior monks.


        The problem is that a variable (i.e. the refrence) can be bound to multiple names.

        So using PadWalker doesn't really help... but I think I have a better idea how to solve it. :)

        Cheers Rolf
