Freedom of Implementation

Previous: LISP Specialties
A required task-level (LISP) function can be implemented as
- a LISP coded function loaded at run time,
- a C coded function which is linked with the LISP interpreter, or
- an external application, implemented as separate executable
Whatever method is used does hardly make a
difference at the interpreter level.
The functionality is always presented as a single LISP function.
