Compiler crashes when use overloaded method with extra args

[MaxGraey]

Example:

class Vec2 {
  constructor(public x: f64 = 0, public y: f64 = 0) {}
  @operator("==")
  eq(a: Vec2, b: Vec2): bool { // non-static but 2 args
    return a.x == b.x && a.y == b.y;
  }
}

class Expect<T> {
  constructor(public actual: T) {}
  public toBe(expected: T): bool {
    let actual = this.actual;
    return actual == expected;
  }
}

const exp = new Expect<Vec2>(new Vec2(1, 2));
assert(exp.toBe(new Vec2(1, 2)) == true);

will crash compiler.

However this will work:

class Vec2 {
  constructor(public x: f64 = 0, public y: f64 = 0) {}
  @operator("==")
  eq(other: Vec2): bool { // 1 arg
    return this.x == this.x && other.y == other.y;
  }
}

or this:

class Vec2 {
  constructor(public x: f64 = 0, public y: f64 = 0) {}
  @operator("==")
  static eq(a: Vec2, b: Vec2): bool { // 2 args but static
    return a.x == a.x && b.y == b.y;
  }
}
