can you provide an example where this (undocumented?) syntax makes a difference?

    Looks like its been superficially improved so there is no difference anymore, which is good. But the output is still wrong, which is bad. For $x=\$y; $y=\$x; the raw call to Data::Dumper->Dump([$x,$y]) used to produce:

    $VAR1 = [ \\$VAR1->[0], ${$VAR1->[0]} ];

    But now it produces what Data::Dumper::Dumper (and what the sub{\@_} trick does) produce:

    $VAR1 = \\$VAR1; $VAR2 = ${$VAR1};

    Wheras Data::Dump::Streamer::Dump produces the correct output:

    $REF1 = \$REF2; $REF2 = \$REF1;

    Hope that explains things.
