I'm late to this thread, but what is wrong with this:
<cffunction ....>
<cfset var tempStruct = "">
<cfset var data = arrayNew(1)>
<cfset var x = 1>
<cfloop index="x" from=1 to=10>
<cfset tempStruct = structNew()>
<cfset tempStruct.foo = "moo">
<cfset arrayAppend(data,duplicate(tempStruct))>
</cfloop>
Won't this handle it just fine?
