> if you use language extensions not documented on [docs.daml.com](http://docs.daml.com) or import `DA.Generics`

I was expecting find an explicit list of the supported extensions on [docs.daml.com](http://docs.daml.com), without luck. But maybe that’s not what is meant here.

Searching for `language extensions` doesn’t turn up anything specific.

Do we have an exhaustive list somewhere?

I think this is only referring to undocumented extensions/features and as such they wouldn’t have documentation.
