Sure, but you wrap that up if you want. A Bank can contain both maps, if you want, and you hide the methods that would update individual maps, only exposing your wrappers that update everything together.

Yeah, I'm not saying it's difficult, I'm just saying that it's weird that there isn't a standard ManyToMany<T1, T2> class in most programming languages, even though a functional (if perhaps not performance-optimal) implementation is straightforward and should be very useful at least for DB mappings.

True, I have implemented it myself multiple times, getting a bit annoyed at its absence without stopping to ask why.
