- The label is not needed in the second snippet.
- x->() is shorter than &{x}().
- &{x} is even shorter if you don't care about @_.
- y while x is shorter than while (x) { y }.
- {x;redo} is shorter than x while 1.
- || is shorter than or.
- Proto not needed for w in second snippet.
sub w(&$){&{$_[1]}while&{$_[0]}}sub d(&){$_[0]}
# then, instead of while (foo) { bar },
w{foo}d{bar};
sub l(&){{&{$_[0]};redo}}sub w{$_[0]||last}
# then, instead of while (foo) { bar },
l{w foo;bar};

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.
