Draft JEP: Keyword Management for the Java Language

Evolving the Java language often means new keywords for new features, 
but new keywords risk breaking existing programs. In the Project Amber 
expert group, Brian Goetz suggested a technique for generating new 
keywords that balances compatibility and readability -- _hyphenated 
keywords_ -- and there is already a language feature raring to use it 
(JEP 354, Switch Expressions).

We have now produced an Informational JEP to record the intent and 
detail of hyphenated keywords, for Feature JEPs may rely on. It also 
captures a policy for managing (that is, stewarding) Java's keywords 
more broadly. Your comments are welcome.
