this is a bug 🐛

the compiler does not detect 果物 as an identifier of the v-for scope

<li v-for="果物 in fluits" :key="果物">
          <button @click="onClick(果物)">{{ 果物 }}</button>
        </li>

and caches the handler

  onClick: _cache[0] || (_cache[0] = $event => (onClick(果物)))

handlers should not be cached when there it depends on v-for scoped variables.
