I believe the variables scope is the only one left that's not a structure in CF5 ... I suspect with intent on the part of the Allaire / MM developers... In previous versions several other scopes were not structures, such as URL and at some point even FORM (Ever wonder why you have a FieldNames variable in your form data?) ... by the time CF5 (or I think even 4.5) was released all of URL, Form, Request, Server, Application, Session and Attributes scopes were exposed as structures. Ever needed to delete (not set to "") a single variable from a persistent scope? In CF4.5 and later it became really easy (I won't get into locking here), <cfset temp = StructDelete(Session,"MySessionVariableName")> ... Useful if you're caching certain information in a persistent scope and then need to delete the cache of just one item so that the application will renew / refresh based on IsDefined() logic (which I avoid if possible, but in some cases it's desireable)...
