When using multiple initializations in a for loop,
I found that scoping didn't work as I expected it would.
For example, in this fake snippet
use strict;
### this code contains an error
for (my $i=1,
my $j = $i + 100;
$i<50;
$i++, $j++) {
print "i=$i j=$j hello!\n";
}
the line my $j = $i + 100;
generates an error because
$i doesn't exist yet. Not a big deal, and trivial to work-around, but can someone explain why scoping works this way here?

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).
