So enjoyable

While hacking GrailsCrowd today, I caught myself thinking that programming in Groovy is such an enjoyable experience (for me). Take this method for example:

// Social feature: gets a list of 'colleagues' working on the same projects as *this* member
   def getProjectColleagues() {
       getActiveProjects().collect
           {it.participants}.flatten().findAll
               {it.participant.id != this.id}.collect {it.participant}
   }

Is it possible to navigate "deep" object graph and express the same intent with the similar compactness in 'raw' Java code? I think not :-)

Later...
