Here's a neat method:
<cfset lst = "a,list,with,with,duplicate,elements">
<!--- We shall be using a struct as a set! --->
<cfset set = StructNew()>
<cfloop index="elem" list="#lst#">
<cfset set[elem] = "">
</cfloop>
<cfset lst = StructKeyList(set)>
Et, voil�!
After all, a map is just a set with values attached to each one of the
elements. For example, the HashSet in Java is internally implemented
using a HashMap.
