This one looks like someone who didn't know about fancier things like IPC::Open2, not someone trying to be tricky. He's right about combining statements with "and" though.
he was talking about C::Scan originally written by Ilya Zakharevich (ilyaz) and now being maintained by hv (the current perl pumpking). I doubt they didn't known about IPC::Open2!
For me it's understandable, they were just focusing on the important thing, parsing the C code, and leaving secondary things like portability for later... or just going for a "it works for me but patches are welcome" mode.

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).
