  my $COMMA = qr/(?:,|=>)/;
  my $SIGIL = qr/$@%*&/;
  my $ATOM  = qr/[[:word:]]+/;
  my $SEP   = qr/::/;
  my $VAR   = qr/$SIGIL$SEP?$ATOM(?:$SEP$ATOM)*/;

  my $WITH_PARENS = qr/$DUMPER_FUNCTION\s*\(([^)]+)\)/;
  my $VAR_LIST    = qr/$VAR\s*(?:$COMMA\s*$VAR)*/;


That seems more trouble than it's worth and I assume it's buggy. 
Patches welcome :)
