Lisp was renowned for groundbreaking language innovations; its contributions permeate modern programming languages. However, the language was unique in its ability to blend code and blur boundaries within a system due to an everything-available-all-the-time approach. Additionally, Lisp became notable for its pervasive interactivity and REPL, allowing for an intuitive, user-friendly interface uncommon in other languages. A significant characteristic of Lisp is its homeoiconicity, which enables users to create code that produces code via metaprogramming. This process is facilitated by the program’s AST and literal representations of the program’s core language data structures. Consequently, Lisp has a distinct position in the world of language design innovation.
