const source = `
namespace "mandelbrot"

interface {
  update(width: u32, height: u32, limit: u32): [u16]
}`;

const doc = parse(source, undefined, { noLocation: true });
const errors = validate(doc, ...CommonRules);

if (errors.length > 0) {
  errors.map((e) => console.log(e.message));
} else {
  const context = new Context({});
  const writer = new Writer();
  const visitor = new AbstractVisitor();
  visitor.setCallback("Operation", "", function (context) {
