Interesting. Here are the results of your benchmark (-Set::Scalar) run using my default perl (5.10.1 64-bit): C:\test>1064178-b.pl
Rate listCompare OPdiff hash_grep OPdiffModified OPdi
+ff_undef using_vec
listCompare 12.9/s -- -86% -93% -94%

And this using 5.18 64-bit (also minus List::Compare): C:\test>\perl5.18\bin\perl 1064178-b.pl

They've really screwed up vec. ( Along with substr and a bunch of others :( )
With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
