I've used this with heredocs in CGI scripts.
Example:
#!/usr/bin/perl
sub top_html {
return "<html><head>$_[0]</head><body>";
}
print <<EOF;
@{[top_html("catchy title")]}
blah..
EOF
Explanation:
@{ somearef } takes an array reference "somearef" and dereferences it.
[ somearray ] takes a list "somelist"
and makes an array ref of it.
@{ [ function() ] } takes the
list returned by "function()" and wraps it in
a way that is interpolatable by quotemarks.

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).
