Note that my first statement is *not* 'drivel':

<cfif isDefined("myVar")>
    <cfset result = "the value myVar is " & myVar>
<cfelse>
    <cfset result = "">
<cfif>

The above works. The following, with iif(), does not:

<cfset result = iif(isDefined("myVar"),"the value myVar is " & myVar,"")>

iif() will evaluate all three arguments first, *then* return either
the 2nd or 3rd argument based on the value of the 1st argument.
