"e.g. instead of print "<$element->{name}>";, use print '<', $element->{name}, '>';
Personally, I'd prefer:
printf '<%s>', $element->{name};
Update: just for the heck of it, this ain't too bad either:
print "<$_>" for $element->{name};
Using postfix for to temporarily alias $_ is an idiom I don't see used very much, but is quite cute, and in this case has no speed penalty (quite the opposite in fact)...
use strict;
use Benchmark ':all';
open $::dummy, ">", \$::data;
cmpthese(100_000, {
print_for => q[ $::data = ''; print {$::dummy} "<$_>" for "a" ],
printf => q[ $::data = ''; printf {$::dummy} "<%s>", "a" ],
});
__END__
Rate printf print_for
printf 7663/s -- -79%
print_for 36765/s 380% --
(PS: kcott's follow-up was posted before this update, so please don't read it as necessarily endorsing the for postfix technique.)
package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name

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).
