sure the key will remain as a local copy but that also means it's no longer
pointing to the origional copy, yes?
so "<cfset objA = objB />" is just making "objA" as a reference to "objB" since
they're complex values?
the same holds for "<cfset _config = arguments.objConfig />", yes?
imagine some decorated objects ("controller" with a "service" and a "config")
stored in, say, application scope.
if I pass a reference to the "config" as an argument to the init of the
"service" - *and then* clear that config struct key from the "controller", have
I still got a reference to the origional from deep within the "service"?
thanx

(code written from memory - excuse the errors)
<cfcomponent displayname="objController">
<cfset _config = structnew() />
<cfset _service = structnew() />
<cffunction name="init">
<cfset _config = createObject("component", config).init() />
<cfset _service.student = createObject("component",
student).init(objConfig="#_config#") />
<!--- so what happens if I delete the passed CFC reference here? --->
<cfset structDelete("variables", "_config") />
<!--- have I just passed in a reference to a (now) non-existant object
or forced a copy to be made in the service --->
<cfreturn this />
</cffunction>
... ... ... etc ... ... ...
<cfcomponent displayname="objStudent">
<cfset _config = structnew() />
<cffunction name="init">
<cfargument name="objConfig" type="struct" />
<cfset _config = arguments.objConfig />
<cfreturn this />
</cffunction>
...etc...
NOTE: why bother doing this? so I can call up to it within the services - like
this
<cfset dirRoot = _config.getRootPath() />
which means that if I run "_config.setRootPath(path)" elsewhere, the changes
should be picked up here in "the deep"
