It even turns out that there is no speed difference. (I expected *some* advantage to the inline string, because there'd be an extra indirection. But it's lost to the method call overhead.)
use Benchmark;
package Bar;
sub new {};
package main;
my $obj;
my $class = "Bar"; # "our" *is* slower, though.
timethese -1, {
bareword => sub { $x = Bar->new() },
var => sub { $x = $class->new() },
};

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).
