This seems to do the trick
use Data::Dumper;
my @a = split ' ', q[foo bar baz quux];
my $le = my $h = {};
for(0 .. $#a - 1) {
$le->{ $a[$_] } = { $a[$_ + 1] => {} };
$le = $le->{ $a[$_] };
}
print Dumper $h;
__output__
$VAR1 = {
'foo' => {
'bar' => {
'baz' => {
'quux' => {}
}
}
}
};
Although are you sure this is the trick you want to be performing?

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).

or How to display code and escape characters
are good places to start.
