Though I highly doubt Sean's challenge included Bluedragon...
I've had to use evaluate on BD with a cfc, but that's probably because
I misunderstand how "this" is supposed to work in cfc's nowadays (let
alone if it's the same on mx and bd):
<cfloop collection="#this#" item="x">
<!--- evaluate is for bd6.1 --->
<cfset ispect = evaluate('this.' & x)>
<cfif isSimpleValue(ispect) or isStruct(ispect) or isArray(ispect)>
<cfset variables.localvars[x] = ispect />
</cfif>
</cfloop>
It's used when trying to save the state of a CFC to an xml file.
this[] syntax didn't work, but I seem to remember someone saying that
"this" in a cfc is wrong anyway - so it's probably wrong in the first
place :-/
BD6.1 btw
<cfset ispect = this[x]> works on cfmx6.1
