| * A mixin application of the form S with M; defines a class C with superclass |
| * S. |
| * A mixin application of the form S with M1,...,Mk; defines a class C whose |
| * superclass is the application of the mixin composition Mk−1∗...∗M1 to S. |
| * In both cases above, C declares the same instance members as M (respectively, |
| * Mk). |
| * @description Checks that it is a compile error to derive a mixin from a |
| * class which has a superclass other than Object, even if mixin has all of its |
| * instance variables |
