+Now it is up to every derived `Shape` to manipulate the protected data correctly.
 This has been popular, but also a major source of maintenance problems.
 In a large class hierarchy, the consistent use of protected data is hard to maintain because there can be a lot of code,
 spread over a lot of classes.
 The set of classes that can touch that data is open: anyone can derive a new class and start manipulating the protected data.
 Often, it is not possible to examine the complete set of classes so any change to the representation of the class becomes infeasible.
 There is no enforced invariant for the protected data; it is much like a set of global variables.

+if `f()` throws an exception different from `X` and `Y` the unexpected handler is invoked, which by default terminates.
 That's OK, but say that we have checked that this cannot happen and `f` is changed to throw a new exception `Z`,
 we now have a crash on our hands unless we change `use()` (and re-test everything).
 The snag is that `f()` may be in a library we do not control and the new exception is not anything that `use()` can do
 anything about or is in any way interested in.
 We can change `use()` to pass `Z` through, but now `use()`'s callers probably needs to be modified.
 This quickly becomes unmanageable.
-Alternatively, we can add a `try`-`catch` to `use()` to map `Z` into an acceptable excption.
+Alternatively, we can add a `try`-`catch` to `use()` to map `Z` into an acceptable exception.
 This too, quickly becomes unmanageable.
 Note that changes to the set of exceptions often happens at the lowest level of a system
 (e.g., because of changes to a network library or some middleware), so changes "bubble up" through long call chains.
 In a large code base, this could mean that nobody could update to a new version of a library until the last user was modified.
