I like to write code that works under taint because it increases the number of contexts where my code can be used.
You may already be aware of this, but one can significantly reduce the number of pointless taint complaints simply by setting $ENV{PATH}=''; $ENV{CDPATH}=''; or other known (untainted/detainted) value. This applies to a few other variables, like IFS, as well. See perlsec for details.
Best, beth

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).
