+If you have an object of type `FooMock` in scope, you'll get the *record field*, not the *interface member*.
+You need to cast it to `IFoo` before using it (or pass it into a function which takes an `IFoo`):

+thing.Field "hello" // the right one: this call does get recorded in the mock, because this is the interface member
