bradcathey,
There are lots of ways in which $#array can be useful otherwise it wouldn't exist in the language. My point was more about correctness. For instance, if I am doing the following:
my @ucase = grep { $_ eq uc() } @words;
my $cnt = @ucase;
I have the count of uppercase words, making all appropriate assumptions about @words. I would need to use $#ucase + 1 * since it doesn't produce a count of elements otherwise. This was not clear from the post that I was replying to.
* As RazorbladeBidet points out, modifying $[, is one highly discouraged way of accomplishing the same thing.

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).
