Perl 5
while <STDIN> { ...
In Perl 5, the parens are not optional. And please use a monospaced font for code :).
dot/underscore
String Concatenation from . to _. Note: whitespace is neccessary.
Only if there's a \w character next to it. $foo{bar}_$foo{bar} will be possible, but $foo_$bar will not (or at least not DWIM).
'for' is now a shortcut for 'foreach'.
I don't know if shortcut is the right word, but currently, for and foreach are exactly the same. That is, foreach (EXPR;EXPR;EXPR) and for (LIST) work.

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.
