Can you expand on what you've run into with references in the Perl debugger?

  print $ref REFERENCE$HASH Or something like that, it's been a while. I'm spoiled by the Javascript debuggers built into Chrome & Firefox, although I'm not sure about the Node.js debugger. Is there a shell (either graphical, or "Borland Turbo Debugger for DOS" style) for perl -d ? (even the "view locals" command in gdb for C presents data more quickly than the built in perl debugger)
