Try -MO=Deparse to see what perl thinks of your code:
$ perl -MO=Deparse 443218.pl
my(@l) = ('10', '20', '30');
foreach $_ (@l) {
my $t += $_;
}
print $t;
443218.pl syntax OK
where file 443218.pl contains
$ cat 443218.pl
use warnings;
use strict;
my @l = qw/10 20 30/;
my $t += $_ foreach @l;
#my $t;
#$t += $_ foreach @l;
print $t;
Update: Added the contents of the file given to -MO=Deparse for clarification.

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).
