This doesn't answer your question directly, but if you are really going to
test for the existence of a variable, and create it if it doesn't exist, I'd
suggest using <cfparam> which will accomplish both of those things in one
step. I only used IsDefined if I want to check for the existence of a
variable, and I'm NOT going to create it if it doesn't exist.

Subject: IsDefined('') v. <cfset>
Anyone have any idea whether an IsDefined('') 'costs' more than a <cfset>?
i.e. Which is more work for the server - to test for the existence of a
variable (and create it if it doesn't exist) or create or overwrite it
anyhow?
Thanks.
