It only makes sense if the mapping is a bijection (math term). It's a really rare property, meaning zero information loss.

No, It's very common. We can bind local property with part of json which bind with local storage as example. So write to property will change json at local storage and affects to same property of another instance of same app. Example:

class Profile {

    @ $mol_mem
    store() {
        return new $mol_store_local({
            profile: { name: 'Anon' }
        })
    }

    @ $mol_mem
    name( next?: string ) {
        return this.store().sub( 'profile' ).value( 'name', next )
    }

}

const profile = new Profile

profile.name() // 'Anon'
profile.name( 'Jin' ) // 'Jin'
// restart app
profile.name() // 'Jin'
localStorage.getItem( 'profile', '{ "name": "Anon" }' )

Bi-directional bindings re-invented? Fair enough.
