Here's another way that produces a tree whose leaf nodes have undef values:
sub paths2treeREPEL {
my %tree;
for (@_)
{
my $last = \\%tree;
$last = \$$last->{$_} for split /\\/;
}
return \%tree;
}
FWIW:

JDP_c 1140/s 29% -- -39% -52%
GF 1867/s 112% 64% -- -21%

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).
