I don't use -T, but I think its use is highly overrated. I don't like -T because I trust my own code, find tainting very restricting and don't like the enormous overhead untainting involves.
If there's one thing I hate, it's code like:
($var) = $var =~ /(.*)/s; # untaint $var
# ... or ... (and the following idiom is used a lot more often (why?))
$var = $1 if $var =~ /(.*)/s;
But code like that is seen very, very often. And that's because tainting is often recommended without telling it's not needed when you don't do system calls.

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).
