> just made it smarter ... without needing the "use re 'eval'":
hm, we seem to be talking about different things
please compare these threads
They show that concatenating literal strings to form an eval group used to work out of the box without use re 'eval' .
Both examples don't include any variables but rely on concats aka .
In detail: Some optimizer converted this
- ''=~ ( '(?{B' . 'EGIN{print "owned"}})' )
into this at compile time
- ''=~ '(?{BEGIN{print "owned"}})'
without complaining. Now it requires use re "eval"

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).
