Removing duplicates from lists (See related posts)

A request for this came up on the CF-Talk list recently. Here's what I came up with.
<!--- The list with want to clean up --->
<cfset lst = "a,list,with,a,few,duplicates">
<!--- Use a struct to build a set of the list elements --->
<cfset set = StructNew()>
<cfloop index="elem" list="#lst#">
    <cfset set[elem] = "">
</cfloop>
<!--- Convert the set back to a list --->
<cfset lst = StructKeyList(set)>

This sort of this should be familiar to all you perlmongers out there.
