I agree. The phenomenon that for
in perl is equivalent to while is best
shown in that for(;<>;){ has the same magic
as while(<>){.
Also I note that until(){ is accepted too,
and it seems to mean until(1){, that is,
it's not executed at all.
Of course, while() means while(1)
only as a prefix while. A suffix while ();
has an empty list in its condition as expected, so it doesn't
execute at all, a suffix while; is an error,
and the results for until is similar.

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).
