in all uses of `CasesOnApp`, we treat `MatcherApp`s the same way, dupliating a fair amount of relatively hairy code (and there is more to come). However, the `MatcherApp` abstraction is perfectly capable of also representing `casesOn` applications, at least for the use cases encountered so far. So lets just (optionally) include `casesOn` applications when looking for matchers, and remove the `CasesOnApp` abstraction completely. |
