D'oh! My fault; the anonymous sub block needs to be delimited with a semicolon. Code changed.
Here's a minimal example of what I think you're looking for:
#! /usr/bin/perl -w
use strict;
sub foo
{
print "in foo\n";
my $bar = sub {
print "in bar\n";
};
if(0 == @_) {
$bar->();
} else {
for (@_) {
print "foo called with $_; ";
$bar->();
}
}
}
&foo();
&foo(qw(one two three));

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).
