@Userroles and multiple userroles

We all know of using @userroles for hiding design elements using @Ismember or @Isnotmember. But @Isnotmember does not check for multiple roles. Here's an easier way.

 <style type="text/css"><!--
.TPtext { color: #000000; 
background-color: #FFFFFF; }
.TPkeyword1 { color: #0000FF;
 background-color: #FFFFFF; }
.TPstring { color: #008080; 
background-color: #FFFFFF; }
.TPbracket { color: #FF0000; 
background-color: #FFFFFF; }
.TPoperator { color: #000000; 
background-color: #FFFFFF; }
--></style>


Suppose a field 'Status' has to be 
hidden to all except for people 
with roles "[Admin]" or 

"[Superuser]". This could be usually 
done by using 
<span class="TPtext">
 <pre>
 @<span class="TPkeyword1">
Isnotmember</span><span class=
"TPbracket">(</span><span 

class="TPstring">"[Admin]"</span>;
@<span class="TPkeyword1">userroles
</span><span 

class="TPbracket">) </span>| @
<span class="TPkeyword1">Isnotmember
</span><span 

class="TPbracket">(</span>
<span class="TPstring">"[Superuser]"
</span>;@<span 

class="TPkeyword1">userroles
</span><span class="TPbracket">)</span>
 </pre>


Instead we could use the permutated 
equality on lists as follows:
<pre>
!<span class="TPbracket">(
</span>@<span class="TPkeyword1">
userroles</span>*<span 

class="TPoperator">=</span>
<span class="TPstring">"[Superuser]"
</span><span 

class="TPoperator">:</span>
<span class="TPstring">"[Admin]"
</span><span 

class="TPbracket">)</span>
</pre>
</span>
This is lot more readable and shorter.
