Hey, thanks for the PR. I'll need to review what impact supporting blank string literals as path nodes and removing clean() might have on existing use cases.

Can you give me a use case for blank string literals as a key other than because it's valid? I've never seen anyone use them ever and am curious what your use case would be.

Example: i have a situation where a template is:

<div>
  <p block-content="mykey">some content</p>
</div>

So i store content in {mykey: 'some content'}.

However sometimes the template is a single node, so the key is implied.
Since any name would risk the key to be a legit key, i choose to store

<div class="anothertemplate">some other content</div>

as {"": "some other content"}.

I used to store it as "some other content" (a plain string) but it makes a special case.

Hi ya, just a quick update.... so having reviewed the impact this might have, I would like to support this but need to re-work the implementation so that it is an optional behaviour rather than implicit.
