### What problem does this feature solve? transform a project which has used lots of ' xxx: vm => vm.prop ' as computed options to typescript easier ### What does the proposed API look like? change vue/types/options.d.ts type Accessors<T> to ```ts export type Accessors<T> = { [K in keyof T]: (() => T[K]) | ComputedOptions<T[K]> | ((vm: any) => T[K]) } ``` <!-- generated by vue-issues.
