Is there a language that gets compiled to Java code (not Byte code but Java .. so no Groovy, Scala, Jython, JRuby etc.)?
In other words is there a CoffeeScript for Java?
One of the major flaws I have against Java is that its so damn verbose and that it doesn't have multiple inheritance. It seems reasonably that one could just clean up the syntax add mixins/traits and closures through code generation.
Yeah its not elegant but coffeescript does it.
Yep, Xtend. It's a new language brought to you by the Eclipse folks: http://www.eclipse.org/xtend/
No multiple inheritance (that would be a fundamental change to Java semantics), but lots of syntactic sugar, just like CoffeeScript.
