Hi @sixinyiyu,

Implementing such an API involves a lot of work. We must take into consideration how many widely demanded use-cases this can support and how much work it requires and compare those to make a decision. For your example tho, it's pretty easy to work around by doing:

store.book.map(book => book.author)

which gives the same result.
