On the other hand,
If you want to use horrible and/or (somewhat) obfuscated code, you could try:
sub shifty {
my $v = (shift)-1;
map { return ++$v } map { $v |= $v >> $_ } (1,2,4,8,16);
}
or alternately (the readable version):
sub shifty2 {
my $v = (shift)-1;
$v |= $v >> $_ foreach (1,2,4,8,16);
return ++$v;
}
i don't know why i was compelled to post that, but i knew one could reduce the repition and possibly obfuscate the code a little with some obviously useless uses of map doing things it wasn't meant to do...

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.
