Ok, I'll bite...
#!/perl/bin/perl
#
# coderefs.pl -- Yes you can use strict...
use strict;
use warnings;
use diagnostics;
for (qw(foo bar)) {
($main::{$_} or sub { print "No such sub: $_\n" })->();
}
$_ = 'baz';
$main::{$_}(); # works! but,
&{$_}(); # doesn't...
sub foo {
print "Yes, I'm here.\n";
}
sub baz {
print "I'm here as well.\n";
}
__END__
So my question is why?

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).

are good places to start.
