`#<data>` to match attrless class behavior and look a bit more compact. shan (Shannon Skipper)

I wonder if the inclusion of the String variant could be considered again even though it has been merged? Is there a domain where `"true"` and `"false"` Strings are used? The Rails variant trying to support env vars makes more sense to m... shan (Shannon Skipper)
