Inline statement event handler should be 'return'

[tianjianchn]

What problem does this feature solve?

See @click="doSomething('params')", the generated code will be function($event){doSomething('params')}, no return in it. Normal syntax with method name only has the return. So I think consistent may be better.
And the use case is child component may want to manually call the event handler to get the result, not through this.$emit

What does the proposed API look like?

No added api

You cannot get the return values of events through $emit(). It would not work that way because multiple handlers can attach to a single event.

@sirlancelot You are right. So I use this.$listeners.click($event)

[tianjianchn]

@sirlancelot Maybe $emit() can return the result array if there are multiple handlers? Anyway, that's another topic😀
