Examples of groovy.lang.Closure$WritableClosure

groovy.lang.Closure
Represents any closure object in Groovy.
Groovy allows instances of Closures to be called in a short form. For example:
```
 def a = 1 def c = {a} assert c() == 1 
```
To be able to use a Closure in this way with your own subclass, you need to provide a doCall method with any signature you want to. This ensures that {@link #getMaximumNumberOfParameters()} and {@link #getParameterTypes()} will work too without any additional code. If no doCall method is provided a closure must be used in its long form like
```
 def a = 1 def c = {a} assert c.call() == 1 
```
