<h1><a name="description">DESCRIPTION</a></h1>
<p>This module provides a single function called <a href="../../lib/Pod/perlfunc.html#item_dump"><code>dump()</code></a> that takes a list
of values as its argument and produces a string as its result. The string
contains Perl code that, when <a href="../../lib/Pod/perlfunc.html#item_eval"><code>eval</code></a>ed, produces a deep copy of the
original arguments. The string is formatted for easy reading.</p>
<p>If <a href="../../lib/Pod/perlfunc.html#item_dump"><code>dump()</code></a> is called in a void context, then the dump is printed on
STDERR instead of being returned.</p>
<p>If you don't like importing a function that overrides Perl's
not-so-useful builtin, then you can also import the same function as
pp(), mnemonic for "pretty-print".</p>

<h1><a name="history">HISTORY</a></h1>
<p>The <code>Data::Dump</code> module grew out of frustration with Sarathy's
in-most-cases-excellent <code>Data::Dumper</code>. Basic ideas and some code are shared
with Sarathy's module.</p>
<p>The <code>Data::Dump</code> module provides a much simpler interface than
<code>Data::Dumper</code>. No OO interface is available and there are no
configuration options to worry about (yet :-). The other benefit is
that the dump produced does not try to set any variables. It only
returns what is needed to produce a copy of the arguments. This means
that <a href="../../lib/Pod/perlfunc.html#item_dump"><code>dump("foo")</code></a> simply returns <code>"foo"</code>, and <a href="../../lib/Pod/perlfunc.html#item_dump"><code>dump(1..5)</code></a> simply
returns <code>(1, 2, 3, 4, 5)</code>.</p>
