Linguistic abstraction in Lisp
The are several possible approaches to linguistic abstractions in Lisp
- Incremental approaches
- Each new construct is defined by a function or a macro
- Macros are used for new surface syntax, and in cases where evaluation order issues prevent use of functions
- Fine grained linguistic abstraction
- Total approaches
- Writing an interpreter for the new language or
- Translating the new language to an existing language (compilation)
- Coarse grained linguistic abstraction
