Scope vs Extent

Beitrag von Kineese »

In the slides V4, slide number 90 to 91 the topic is about Scope vs Extent,
At least I guess it's about the Environment-State, so the slides say that the identifier, that binds a value may not be available in the running code, but there can be an other identifier that points to the value.
So to resume it: Values have dynamic extent means that the value keeps in the Env while the Identifier who points to it, can change.

Is that correct?

Basically yes, however the values remain in the store, not the environment.
