_render?

What’s the reason for using the leading _ there?

My initial reaction is that it feels kind of hacky and like a workaround when you prefix names like that, something you would only do internally in your code if needed — not in the public api of your library that your users will have to see. If it’s only a naming convention the Polymer team uses for protected methods I would recommend not polluting lit-element’s public api with that, it is definitely not a well-established naming convention that everyone wants to use.

@Lodin but is it really realistic that the 6 lifecycle methods in lit-element would ever collide with somebody’s public api properties? Enough to warrant the underscores?

Personally, as a React developer I love the idea of lit-element – being able to build web components the way I build React components. But that naming convention is really off-putting, makes it feel like it’s a work-in-progress.
