Joy

- Motivation
  - Simple, elegant, useful, combines good features of Lisp and Forth.
  - "Provably Correct Constructs" Margaret Hamilton, James Martin
  - Backus' Functional Programming (doing math to derive programs)
- A brief introduction to Joy
  - the language
    - stack, literals
    - functions
    - combinators
  - the runtime
    - CLI interpreters
    - Jupyter Notebook kernel
  - Extensions?
    - "Snippets" [hash offset length]
    - Numerical Tower
    - additional datatypes
    - "under the hood" optimizing
- Implementation of Joy Interpreters
  - Compare and contrast Py, Nim, OCaml, Prolog
- Categorical Paradigm
  - Symbolic Interpreter
  - Constraint-based Interpreter
  - "Calculator Mode" Interpreter
  - Type Checking and Inference
  - Compiling
- Compilers (Work-in-Progress)
  - To Python (or other "high" level langauges)
  - To machine code or at least e.g. LLVM IR.
  - Prolog research on compilers
