I voted for string eval. I hate string eval, in any language, because it's misused too often. There are just very few good uses for eval. And a double e flag counts as string eval. I wouldn't mind if string eval had some less obvious syntax. For the very rare valid uses it has, it wouldn't hurt having to go circles to evaluate code.
(I admit, I have used string eval in obfus, like Re: Re: exactly 390 bytes (perl) or One-liner japh (bash).)

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).
