问题 It's said that composition api solves naming conflicts which were brought by mixins. This is what I found on the internet about composition API. export default { setup () { const { someVar1, someMethod1 } = useCompFunction1(); const { someVar2, someMethod2 } = useCompFunction2(); return { someVar1, someMethod1, someVar2, someMethod2 } } } I guess, useCompFunction1() and useCompFunction2 are like mixins. In the example, all is good. but if useCompFunction1() and useCompFunction2() use the
