Random Thoughts

• Paradigm: Mostly pure functional programming language
  • impure blocks, like Rust's unsafe, for now
• Functions
  • Functions are first class citizens
  • Tail recursion & tail call optimization
  • Higher order functions
  • Pipes: (|>)
  • Partial function application/currying
  • Closures
  • Decorators e.g. @memoize
  • Async/Await?
• Type System
  • Types are first class citizens like in Idris
  • Statically typed
  • Strongly typed?
  • Algebraic types (sum & product types)
  • unit i.e. ()
  • No null pointers, Haskell's Maybe<T>.. Some<T> or None
  • Strong type inference
  • Hindley–Milner type system?
  • Generic types? Parameterized types?
  • Dependent types?
    • Aiming for types that are so powerful you can prove mathematical theorems with morph
    • forall, there exists
• Evaluation Strategy
  • Everything is an expression
  • Lazy execution
  • Generators?
  • Zero cost abstractions
  • Implicit parallelism
    • Expressions are thread-safe
    • Static cost estimation
    • Cyclomatic complexity?
    • Theoretical limits: Amdahl's law
• Control Flow
  • Pattern Matching
    • Match blocks, like Rust's
• Memory management
  • Rust's ownership model?
  • Garbage collection?
• IO
  • Monads?
• Vectorization/Array Programming
• Metaprogramming
  • AST-based macros
• Backend
  • LLVM
• Formal verification?

Standard Library

• Implicitly imported

Functions

• all(): Do all elements satisfy a condition?
• any(): Does any element satisfy a predicate?
• map()
• reduce()
• filter()
• max()
• min()
• reverse()
• sum()
• zip()

Types

1. List (+, append, [], all, any, filter, foreach, indexOf, join, len)

Abstract Algebra

Operations, Groups, Rings, Fields, Vector Spaces, etc

IO

Regex

Pseudo-random number generator

ML

Parser Combinator
