For the background on my reasoning, the popular shift towards dynamic languages makes me wonder how far off a C#-like dynamic feature is for Java too. I hedge my bet that it will eventually happen -- years upon years away -- when more serious use cases are found. Thus, to prevent the case of split packages (java.dyn and java.lang.dyn), I chose to bring up the discussion.
Ben and John, thank you for your responses. It is good to understand your vantage. Paul
