Project Coin: Week 4 Update

Update: Corrected to include Stephen Colebourne's enhanced enhanced for loop proposal.

Further update: Added links to updated large arrays and compile time access proposals.

Project Coin's fourth week saw continued lively traffic on the mailing list. As the submission deadline approaches, a flurry of new proposals were sent in:

• Named method parameters, Paul Martin

• Enhanced for each loop iteration control, Stephen Colebourne

• Loosen Constructor super()/this() call restrictions, Mike Duigou

• Simplified syntax for dealing with parameterized types, J. Lowden

• Compiletime information access (revised), Ruslan Shevchenko

• @Unloadable Class defination, Daniel Cheng

• Large arrays (revised), James Lowden

• Naked dot, Makarenko Alexandre

• Auto-assignment Parameters , Mark Mahieu

• Unchecked Exceptions as Subclasses of Checked Exceptions (revised), Alan Snyder

• Narrow Hexadecimal and Binary Integer Literals, Bruce Chapman

• Return 'this', Marek Kozieł

• Improved Support for Optional Object Behaviors at Runtime, Alan Snyder

The field of over two dozen proposals previously sent in over the first three weeks of Project Coin was narrowed to six proposals still in consideration for inclusion in JDK 7. The proposals submitted this week and until the end of the call for proposals period will be similarly evaluated for their appropriateness to be added to the language. Finally, the combined list of candidate changes will be produced.
