SimpleDB - Like Indexed DB, but Simple

A simple asynchronous data store.

STATUS: This is a thought experiment, not a serious proposal. Would basic async storage like this be useful? With this plus some locking primitive, could you build Indexed DB?

Like Indexed DB:

• rich value types - store anything you can structured clone
• rich key types - Number, String, Date, Array (of other key types)
