Author here, thanks for the feedback. This is v. much a work-in-progress, I'm in the process of trying to build something non-trivial with it. Just a couple of things to address in general from the comments so far:<p>- I'm aware of dhall, jsonnet and friends, I think they're cool, but I think the most important for me is this is <i>just js</i> - that means nothing new to learn + you can use it from front end code + free linters etc.<p>- I think the to-html bit is important, this is something I tangentially talked about in more detail here - <a href="https://leontrolski.github.io/dom-syntax.html" rel="nofollow">https://leontrolski.github.io/dom-syntax.html</a>. There was some discussion on hacker news about that one too, again, I think the important "feature" is that it's <i>just js</i>. Again, to me that's really important, so hiccup, jsx, etc don't cut it.
