title: Where can I find an implementation of Java EL 3.0
body: <p>The Expression Language version 3.0 is currently being designed. It adds various cool features like mapping and filtering collections by a lambda expression. Spring EL has a comparable feature which does not use lambdas though.</p>
  
  <p>Despite googling for a (reference) implementation of EL3 I couldn't find anything, Is there an (reference) implementation available or at least underway?</p>
  
  <p>Otherwise I may need to use Spring EL for now, I guess.</p>
  
  <p>Thanks</p>
