built-in method using MethodHandle behind the scenes

	@Params("value, block=false")
	public static Object EqualRange(Object self, Object a, Object b) {
	Range r = ((SuContainer) self).equalRange(a, b);
	return SuContainer.of(r.left, r.right);
	}

old way of implementing built-in methods

	public static class EqualRange extends SuMethod2 {
	{ params = new FunctionSpec(array("value", "block"), Boolean.FALSE); }
	@Override
	public Object eval2(Object self, Object a, Object b) {
	Range r = ((SuContainer) self).equalRange(a, b);
	return SuContainer.of(r.left, r.right);
	}
	}
