Description

Given the following annotation type declaration in Java:

public @interface Timeout { 
  int value(); 
  TimeUnit unit(); 
} 

In Java I can write:

@Timeout(5, unit = TimeUnit.SECONDS) 

The Groovy equivalent is slightly more verbose:

@Timeout(value = 5, unit = TimeUnit.SECONDS) 

Groovy should also allow the former style.

Additionally, Jochen has suggested to allow the following styles (see http://www.nabble.com/Annotation-syntax%3A-Java-vs.-Groovy-to17217160.html):

@Timeout(5, unit: TimeUnit.SECONDS)
@Timeout(value: 5, unit: TimeUnit.SECONDS)
