v1.2.0

Enhancements

• Supports of instance of pattern matching (#476)

// Input
if (o instanceof Integer i || p instanceof Point || q instanceof Circle c || r instanceof Square) {
  formatted = String.format("int %d", i);
} else if (o instanceof Long l) {
  formatted = String.format("long %d", l);
} else if (o instanceof Double d) {
  formatted = String.format("double %f", d);
} else if (o instanceof String s) {
  formatted = String.format("String %s", s);
}

// Output
if (
  o instanceof Integer i ||
  p instanceof Point ||
  q instanceof Circle c ||
  r instanceof Square
) {
  formatted = String.format("int %d", i);
} else if (o instanceof Long l) {

    this.length = length;
    this.height = height;
  }

  @Override
  public double area() {
    return length * height;
  }
}

// Output
public sealed class Rectangle implements Shape permits Square {

  private final double length;
