I don't get it. When Purity=0 DD, doesn't claim to reevaluate correctly and it's frequently more readable. When Purity=1, it seems to work perfectly for me.

Here's something that takes your examples above, DDDumps them with Purity=1 and reevals the string and then shows the Streamer version of the original and of the evaled.

```use Data::Dumper;
use Data::Dump::Streamer;
\$Data::Dumper::Purity=1;

my (\$x,\$y);
\$x=\\$y;
\$y=\\$x;
test([\$x, \$y]);

my \$ary=[];
\$ary->[0]=\\$ary->[1];
\$ary->[1]=\\$ary->[0];

test(\$ary);

sub test
{
my \$VAR1;
my \$s = shift;
my \$d = Dumper(\$s);
my \$s2 = eval "\$d;\\$VAR1";
die \$@ if \$@;
print "original---------------\n";
print Dump(\$s);
print "DDed---------------\n";
print Dump(\$s2);
print "\n"
}
__END__
original---------------
\$ARRAY1 = [
\do { my \$v = 'V: \$ARRAY1->[1]' },
\do { my \$v = 'V: \$ARRAY1->[0]' }
];
\${\$ARRAY1->[0]} = \$ARRAY1->[1];
\${\$ARRAY1->[1]} = \$ARRAY1->[0];
DDed---------------
\$ARRAY1 = [
\do { my \$v = 'V: \$ARRAY1->[1]' },
\do { my \$v = 'V: \$ARRAY1->[0]' }
];
\${\$ARRAY1->[0]} = \$ARRAY1->[1];
\${\$ARRAY1->[1]} = \$ARRAY1->[0];

original---------------
\$ARRAY1 = [
'R: \$ARRAY1->[1]',
'R: \$ARRAY1->[0]'
];
\$ARRAY1->[0] = \\$ARRAY1->[1];
\$ARRAY1->[1] = \\$ARRAY1->[0];
DDed---------------
\$ARRAY1 = [
\do { my \$v = 'V: \$ARRAY1->[1]' },
\do { my \$v = 'V: \$ARRAY1->[0]' }
];
\${\$ARRAY1->[0]} = \$ARRAY1->[1];
\${\$ARRAY1->[1]} = \$ARRAY1->[0];

The first one comes out identical. The second one is not textually identical but if \${\$x} = \$y means the same thing as \$x = \\$y then I can't see what DD did wrong. Do they mean the same thing?

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

• Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
• Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
• Read Where should I post X? if you're not absolutely sure you're posting in the right place.
• Posts may use any of the Perl Monks Approved HTML tags:
a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
• You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
 For: Use: & & < < > > [ [ ] ]
• Link using PerlMonks shortcuts! What shortcuts can I use for linking?
