The solution is that the source lines they are not in order, but the line numbers are still reliable:
(Cough)
$ cat /tmp/p
for (
$var1++;
$var2++;
$var3++
) {
$var4++;
}
$ perl -MO=Concise,-src /tmp/p | grep var
/tmp/p syntax OK
3 <#> gvsv[*var1] s ->4
f <#> gvsv[*var2] s ->g
# 6: $var4++;
9 <#> gvsv[*var4] s ->a
c <#> gvsv[*var3] s ->d

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.
