in chapter List, the List should never be part of a struct

[JameWade]

List should never be part of a struct - rather, it should only be used when interacting from / to storage. Otherwise, the internal storage addresses of elements in the struct will collide!! please look this issue https://github.com/keep-starknet-strange/alexandria/issues/226

Storage structs of smart contracts are a bit different, see there: https://docs.starknet.io/documentation/architecture_and_concepts/Smart_Contracts/contract-storage/#storage_variables

You can refer to the Store implementation of List here: https://github.com/keep-starknet-strange/alexandria/pull/127
