Here is one method:
my %bits;
my @fields= qw( organization report poise hair swimsuit
question bribe connections );
@bits{@fields}= map { 1<<$_ } 0..7;
sub mask {
my $mask= 0;
$mask |= $bits{$_} for @_;
return $mask;
}
my $byte= 0;
foreach my $field ( keys %bits ) {
$byte |= $bits{$field} if $obj->{$field} =~ /\S/;
}
# ...
if( $byte & mask(qw( organization swimsuit question bribe ))
== mask("organization") ) {
# ...
} elsif( $byte & ~mask("question")
== mask("swimsuit") ) {
# ...
} else {
die "Contestant cheated!\n";
}

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).
