Oh dear... It's unfortunate that Ben documented something that wasn't even
supposed to be legal...

To be honest, this sort of code is really bad practice - multiple
operations kludged together like that. Any programmer on my team who did
that would be taken out a summarily shot! (to misquote Andrew Koenig)
After all, 'iif()' is already verboten here by our coding guidelines, as
is 'evaluate()' (unless you can *prove* you need to use it). These
constructs lead to ugly, unmaintainable code.
It's much, much clearer to write:
<cfif x>
<cfset result = 5/>
<cfset z = arg1/>
<cfelse>
<cfset result = 10/>
<cfset z = arg2/>
</cfif>
or:
<cfscript>
if ( x ) {
result = 5;
z = arg1;
} else {
result = 10;
z = arg2;
}
</cfscript>
You should bear in mind that your original code is akin to this in C/C++:
result = x ? (z = arg1, 5) : (z = arg2, 10);
No self-respecting C/C++ programmer would write such a monstrosity!
