Curl Docs

I agree with Robert in the meaning that first-time users of Curl could easily have difficulty understanding where and when should they use {value} to evaluate an expression, although I have already been used to the usage of it and find it's really great .

The difficulty for understanding {value} is especially obvious when using at the top level of a curl applet file. To understand this, a user must know a DefaultDocument or PlainDocument will add an object without being defined with a varirable to it's layout container (a TextFlowBox) by default , while a variable definition will be kept as a variable only and value of this variable won't be added to it's layout container implicitly. So when you want a variable to be added to a DefaultDocument or PlainDocument, eithier use {value var} at the top level of the *Document, or wrap this variable with another Graphical container like a Fill or Frame or anything else, which is then instantiated directly at the top level of *Document without being assigned to any variable.

Am I complicating this topic ?
