I like that better than expecting a ->param, since that breaks it away from the contract of purely hash->hash. Adding a branch breaks no contracts
sub build_cgi_struct
{
my ($iv, $errs, $conf) = @_;
use Scalar::Util qw(blessed);
my $blessed = blessed $iv;
my $splitnull = 1;
if( $blessed and UNIVERSAL::can( $iv, 'param') ){
$splitnull = 0;
if( $iv->isa('CGI') ){
$iv = $iv->{"param"} ; # cheat :)
} else {
$iv = { map { $_ => [ $iv->param($_) ] } $iv->param };
}
}
...
... if $splitnull;

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
