It's sort of similar to regular pattern-matching, but sadly not built for ergonomics :(
The node pattern matching was ok, but as far as i can recall, there could be multiple matching patterns scattered in lots of places (a 180deg turn compared to most FP pattern matching that aim for exhaustiveness ?)
