What is the difference between this and SI-6398?

@heathermiller said:
The idea was that from the point of view of AnyVal as a type (not knowing anything about value classes), you can now in 2.10 suddenly extend AnyVal. So someone who comes across someone else extending AnyVal in some arbitrary code somewhere would need to make the connection between that and value classes, and googling AnyVal doesn't provide anything of use. So, the idea was to bridge the concepts.

However, I realize that since this text would so short, it'd probably be best to just add this info to the AnyVal Scaladoc with a pointer to the short value classes guide that you just wrote.

That said, I can take this and write the AnyVal Scaladoc.

If anyone would rather it be organized differently- suggestions welcome

Makes sense. You can also now extend Any to define a universal trait.
