just a thought: do we have use cases when callback should return bool indeed?

Maybe we should switch default and treat callbacks as void unless a special
annotation is added.

WDYT?

Looks like generated WebKit bindings always ignore the value returned from
JavaScript. I strongly suspect we should just switch to void for all the
callbacks instead of adding suppressions to dart.idl.
