instead of wasting the trash scalar, you can use LHS undefs:
(undef, $foo, undef, undef, $bar) =(1..5);
print "$foo $bar";
but in general, I will use split 'in parens with brackets' as you mentioned. It's pretty direct, you don't waste any characters dealing with elements that you're ignoring.
($foo, $bar) =(1..5)[1,4];
print "$foo $bar";

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).
