Scheme in Scheme
The
eval
and
apply
primitives
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
