LispE: A Novel Lisp Dialect with Pattern Matching and Logic

LispE, a modern Lisp dialect developed by Naver, distinguishes itself from traditional Lisp implementations like Common Lisp, Scheme, and Clojure through innovative constructs: defpat, defmacro, and defpred. LispE extends Lisp's flexibility and macro system with advanced pattern matching, enhanced macro capabilities, and logic programming elements. defpat enables defining multiple functions under the same name, each triggered by a specific argument pattern; defmacro simplifies custom syntax creation using pattern matching and a $ operator; defpred integrates pattern matching with predicate-based evaluation and automatic backtracking, blending logic programming into the Lisp framework. Compared to other Lisps, LispE offers superior expressiveness and modularity.
