in the literature, the code and the comments, I often find these notions: * updatable * single-entry * one-shot applied to thunks, functions, closures and lambda expressions on various levels
I have the impression that these are indeed plain synonyms (resp. antinyms) when it comes to thunks and other closures, and indicate whether a dynamic instance of this closure is going to be entered once or more than once.
More code reading¹ indicates that updatable and single-entry are antinyms for Thunks, but other closures are always "not updatable" and "not (necessarily) single entry".
