Why not just place your subs whereever you like, call them from whereever you like without & and with (), and not use forward declarations either? What am I missing? Perl isn't C. This seems to work for me:
#!/usr/bin/perl
use strict;
use warnings;
aaa("Hello world");
sub aaa
{
my $arg = shift;
my $quit = shift;
print("I am aaa, arg = $arg\n");
exit 0 if ($quit);
bbb("hello bbb");
}
sub bbb
{
my $arg = shift;
print("I am bbb, arg = $arg\n");
ccc("hello ccc");
}
sub ccc
{
my $arg = shift;
print("I am ccc, arg = $arg\n");
aaa("hello aaa", 42);
}
__END__

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).
