When comparing the result for exercise 2 with the provided solution I noticed that the Shape type contains Square. The rest of the solutions does not handle this case, causing it be non-total.

It raises the question if it, some how, would be possible to export the Shape type and have shapeView be total?

There was a problem with the provided solution which, as you say, wasn't total. I fixed it during the final editing process though and the code will be updated with the final release.

Good to know it is possible. I will check the final release when it is published.
