For me, it was academic. When some one has a tough problem that I can't
see immediately how to find an answer to, I like to find an answer.
That compulsion gets stronger as the number of "this can't be done"
replies increase. =)
I can't answer for Ed as to what his need is, however. But I can say
that the use Per and I were discussing was trying to evaluate
dynamically what a function should do based on its name.

Now, this looks academic. What would be the use of knowing the name
of variable that stores the memory location of the object's invocation?

Actually, this is quite a bit easier that I thought. This function
will output the names of all the variables (I think) that
reference your
component, given a scope. I got the idea for inserting a UUID from
looking at cfcUnit, so I gotta give credit there. Of course, it will
need to be in your component.
<cffunction name="getTheNameOfTheVariableThatContainsMe"
output="true">
<cfargument name="variablesScope" required="true">
<cfset this.testkey = createUUID()>
<cfloop list="#structkeylist(variablesScope)#" index="name">
<cfif isStruct(variablesScope[name]) and
structKeyExists(variablesScope[name],"testKey") and
variablesScope[name].testKey eq this.testKey>
#name#,
</cfif>
</cfloop>
<cfset structDelete(this,"testKey")>
</cffunction>
