I was addressing the serialization of a cyclic structure more than the mutability of cyclic structures.

The selection of a structure could depend on the required functionality, e.g. if your PCBs might consist of millions of pins, if you want to run discrete simulations, etc. (Having said that, I'm not a fan of immutability for immutability's sake, but this is the Clojure list, and you seem determined, so, I'll assume there's a good reason and let it go at that.)
