Would be nice if someone could show me a case where perl gets confused. I could not create one
Confused by addition:
>perl -wle"@a=1; for ((),@a) { push @a,$_+1; print }"
1
>perl -wle"@a=1; for (@a) { push @a,$_+1; print }"
1
2
3
4
...
Confused by deletion:
>perl -wle"@a=(1,2); for (@a) { pop @a; print qq{<$_>} }"
<1>
>perl -wle"@a=(1,2); for ((),@a) { pop @a; print qq{<$_>} }"
<1>
Use of freed value in iteration at -e line 1.

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
