* Concept
|
|
CLOSOS supports multiple simultaneous global environments, where an environment is a mapping from names to objects (functions, classes, packages).
|
|
|
|
* Key Principles
|
|
- **Isolation by Scope:** Each user or process can operate in a private environment. Redefining a system function (like `print-object`) in one environment does not affect other users.
|
|
- **Dynamic Adaptability:** Facilitates safe experimentation with new features without risking system-wide corruption.
|
|
- **Late Binding:** References are resolved against the current environment at compile/load time, enabling live updates and hot-reloading.
