I know many people will disagree with rule 25. But they are my guidelines,
and that's the way I code. Not just in Perl, but any language that I can
remember programming in allows whitespace between an indentifier and its
indexing operation. Including Python. (Unfortunally, Perl 6 will break
decades of tradition).
The reason is that the eye needs resting points. Whitespace makes it
easier to divide a line of text into chunks and read it. As well as in
natural languages as in code. $foo{bar}[17]{baz} is one big blob, and
it's hard to divide it into its 4 chunks, specially when the subscripts
are a bit more complex. We don't have the tendency to chain words together
in English (unlike in for instance German). Why should we with code?

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).
