  - avoid using JavaScript keyword as property name: "function" in expression :options="(function(){return {...{'a':'b'} }})()"

this is valid ES6. also

none of these pass either

(()=>{return {...{'a':'b'} }})()

and

(()=>({...{'a':'b'} }))()

Vue's expression validation can only parse expressions supported by the Node version you are using, so object spread is not supported unless you use Node 8.6+.
