Yeah, in any modern language with pattern matching stuff like this is absolutely the compiler's job, and can be done pretty well[1] - of course, there are plenty of legacy languages that don't have pattern matching, but seeing as it can be compiled straight to switches and whatnot, even the lowest level languages don't have /that/ much of an excuse.
