It will be a good test case to cover :)

Cheers,

That's great news. Not being able to use default interface methods, especially when working
with libraries using them in Java code, felt limiting.

Hi all,



         The new parser(Parrot) supports default method now. You can find

the new feature at  the enhancedInterface branch of groovy-parser project

<https://github.com/danielsun1106/groovy-parser/tree/enhancedInterface>  (

https://github.com/danielsun1106/groovy-parser/commit/89f45ac86e7945ef81283697b6ed9018e997a045

). If no problem with the implementation, I'll merge it into the master

later.



*Here is an example:*



interface Greetable {

    String name();

    default String hello() {

        return 'hello'

    }

}



class Person implements Greetable {

    @Override

    public String name() {

        return 'Daniel'

    }

}



def p = new Person()

assert 'hello, Daniel' == "${p.hello()}, ${p.name<http://p.name>()}"



      *Another more complicated example can be found at:*

Cheers,
