+#### Schema evolution examples (unions)

+Suppose we have the following schema:

+union Foo { A, B }
+```
+We can add another variant at the end.
+```
+union Foo { A, B, another_a: A }
+```

+However if we add `another_a` anywhere but the end, e.g.
+```
+union Foo { A, another_a: A, B }

+this is not okay. When new code writes `another_a`, old code will
+misinterpret it as `B` (and vice versa). However you can explicitly
+set the union's "discriminant" value like so:
+```
+union Foo { A = 1, another_a: A = 3, B = 2 }
+```
+This is okay.
+
+```
+union Foo { original_a: A = 1, another_a: A = 3, B = 2 }
