You also may use CGI.pm's own escape function:

This is probably irrelevant to this discussion. The a() function is being used, which already escapes its arguments. Or at least CGI.pm version 2.752 does.

+f")'
<a href="&amp;&amp;&amp;">asdf</a>

But that's exactly what nobody wants, as the & of & is treated as parameter delimiter.

#!/usr/bin/perl -w
use strict;
use CGI;
my $q = new CGI;
print $q->header;
print "<pre>\n";
print $_, "=", $q->param($_), "\n" for $q->param;
print "\n</pre>\n";

Update: Just for completeness: a() calls CGI::Util::make_attributes on each attribute, the latter calls CGI::Util::simple_escape for escaping ("&"->"&" and some others). CGI::Util::escape does something different (see my last post).
