expressi

Expression-oriented toy programming language written in Rust

let add = a -> b -> a + b;
let succ = add(1);
let v = succ(succ(succ(1)));

let f = if v == 4 {
  a -> succ(a)
} else {
  a -> a
};
let x = f(10)

In this example, x is evaluated to 11.

TODO

• Refine errors
  • Property organize error variants
  • Get rid of unwrap completely
  • Point where the cause is
• Add EvalConstant transformer which calculates compile-time value
• Implement operators as functions
• User-defined types
  • Tuple
  • Enum
  • Struct
• Multi-line input in REPL
