Was forgetting for a minute that declaring $b there would actually scope it
inside the loop.
This isn't quite true - the output of Deparse is wrong.
The lexical is scoped wider than the loop, as can be seen
here:
$ perl585 -le '$x=99; my $x = $_ for 1..3; print $x'
$
(Note that $::x isn't printed, the lexical $x is instead.)
However, the initialising and releasing of $x is scoped
to within the loop.
That may be construed as a bug. There again, statement modifiers
on my declarations are usally buggy, and are best avoided.
Dave.

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.
