Hopefully I didn't come off aggressively, I was just trying to give you some feedback.

In terms of hyperapp, that is as much compiling as `document.createElement("a")`, which is what your library does, too.

I'm not saying write redundant tests. Tests are more than just one person's psychological comfort. Another great example is if you are accepting PRs into a larger codebase, having tests means you know other people aren't breaking previously working parts of your app. Tests can also work as documentation, since a test describes how pieces of your app should work.

I'm confused why you think any of my suggestions imply that you should make your library heavy/larger/unmanageable.
