Add shorthand usages with object for v-bind and v-on

[qmhc]

Description of Problem

Examples of of v-bind and v-on have no shorthand object usage.

Proposed Solution

Add usage to the example.

Additional Information

I don't sure if this is a valid usage. But I think it also need to explain similarly if this isn't valid usage.

If it's valid usage I think it should be added to example.

Another dispute is about v-slot shorthand. Is the following usage valid?

<MyComp>
  <template #="params">
    {{ params }}
  </template>
</MyComp>

Thanks for the PR.

Using :, @ and # in this way is not officially supported.

I have a PR open in the core repo, vuejs/core#7360, that adds a warning for this.

I'm going to close this, as I believe this is intentionally not documented.
