I doubt Data::Dumper inspects any variable names. It just uses what you give it - or VAR1, VAR2 if it gets nothing.

    I doubt Data::Dumper inspects any variable names.

    It doesn't (as far as I know), and my code example would have been clearer had I not supplied a variable name to  Dump() in contrast to the OP. I just wanted to make the points that  Data::Dumper tries to emphasize repeated references within the data structure it's dumping (as these are usually important), and that even if one could sometimes recover the name of a reference, it probably wouldn't be worth doing.
