Description
Hello,
It would be nice to have support for Java 8 (semi) functional data types as they keep showing up more and more in third party libraries
specifically:
- Monoid instance for Optional, Function and Stream
- Bijection between Java Optional and Scala Option. Java Function and Scala function
- Java 8 Stream has both pure and flatMap method so it maybe possible to provide monad instance for that?
Thanks

Research direction
No files, tests, or entry points are named. Start by reviewing the existing typeclass instances and Java/Scala conversion patterns, then determine the intended scope for Optional, Function, and Stream support. Done means the agreed instances and bijections are implemented with coverage for the listed Java 8 types.
