Question

Is there some way to use default parameters values with closures in Groovy?

This is what I tried so far:

class Persona {     String name      Persona( String name ) {         this.name = name     }      String salute( String salute = 'Hola' ) {         salute + ' ' + this.name     }  }  Persona.metaClass.salute2 = {      String salute = 'Hola' ->         salute + ' ' + name }  p = new Persona( 'john' )  print p.salute() print p.salute2() 

which gives me the following result:

Hola johnnull john 

It seems like the call to salute2() is ignoring the salute default value 'Hola'.

Your code is working fine as you expected with Groovy 1.6-RC2.
