I inadvertently added (what I think would be considered) a breaking change here: #55.

That added some unnamed type class instances, which are only supported in PureScript >= 0.14.2. purescript-react-basic-dom specifies a purescript version at ^0.14.0 and a purescript-web-html version at ^3.0.0, which can apparently resolve to purescript@0.14.0 and purescript-web-html@3.2.0 which are incompatible and leads to the CI breaking for that library: purescript-react/purescript-react-basic-dom#26. I'm raising the issue here since I could imagine other libraries being similarly affected.

I can open a PR that adds names to those instances if that's acceptable.
