It's hard to tell, but you're calling them when you think you're putting them into the array -- that is, at the @procs = (&a1, &a2) line. The solution to this problem is references, as discussed in perlref and perlreftut. As follows:
use strict;
use warnings;
sub a1 {
print("a1\n");
}
sub a2 {
print("a2\n");
}
my @procs = (\&a1, \&a2);
foreach (@procs) {
$_->();
}
perl -pe '"I lo*`+$^X$\"$]!$/"=~m%(.*)%s;$_=$1;y^`+*^e v^#$&V"+@( NO CARRIER'

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).
