Java 7 will have closures!

[2009-11-19] dev, java

These pages have the details:

“Closures after all?” is continually updated with new links and information.
Gafter’s “Closures for Java” has been updated with the new syntax which closely resembles FCM. Thus, the new closures use FCM syntax and (a simplified version of) Gafter’s type system. Correction: Gafter’s spec was written 2 weeks before Devoxx, as an attempt at a compromise between the competing proposals.
Reinier Zwitserloot has more background on how everything came about.
Update 2009-11-22: Stephen Colebourne gives an overview of the current situation.
Update 2009-12-03: Mark Reinhold posts “Closures for Java: The Q&A”.
