Data::Dumper::Simple - this is a nice module, but it uses source filters so it's correctness is much less sure than more traditional modules.

You are absolutely correct that it uses a source filter. However, I not only state this clearly in the documentation, I also note that this module is for debugging. For that purpose, it's well-suited to its task. I have never recommended it for any other purpose.

As an alternative, you can try my Data::Dumper::Names. This module does not use a source filter, it's much more limited and sometimes does not provide correct output. However, I've never received any clear bug reports which isolates the problem and since there's not much interest in it, I haven't really pursued it.
