You stopped reading too soon, then. There is much parallelism which could be exploited by having (say) Perl6 constructs be natively parallel, for example the hyperoperators, and grep/map.
Also, having real, painless userspace "threads" (i.e. cooperative multitasking) would be a huge benefit too.
Your reaction is exactly the point that BrowserUk is trying to make, or at least how I interpret it - actually and transparently using and supporting threads is an important asset for a programming language. Having to manually implement IPC, like you have to do if you want to keep on using fork and still reap the benefits of parallelism is a pattern and hence a weakness in the language.

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).
