Common Lisp is fully typed and AOT compiled, allowing strict type assignments for variables and functions.
Types in Common Lisp are sets, and data values can belong to multiple types simultaneously.
Common Lisp performs type checking at both runtime and compile-time to prevent errors.
Type hints can be used to optimize assembly code, with the compiler using them for better performance.
Common Lisp distinguishes between types (compatibility families) and classes (internal data implementations).
Classes in Common Lisp support inheritance, allowing child classes to act as their parents.
Methods in Common Lisp are associated with generic functions, not tied to specific classes.
The behavior of functions and data in Common Lisp is guaranteed by the type system, not the underlying implementation.
Common Lisp's type system and class hierarchy provide flexibility and optimization opportunities without exposing low-level details to developers.
