Pattern matching is great when working with data structures. Compare [Haskell](https://github.com/dcurrie/lobster-bbtree/blob/master/bbtree.lobster#L97-L98) and [Lobster](https://github.com/dcurrie/lobster-bbtree/blob/master/bbtree.lobster#L119-L125) versions of a btree double rotation, for example. And even this is only possible because I defined...
