I  really enjoyed that post.  It might have been composed by Mark
Twain were he a computer programmer.

Amen. One of the almost miraculous things about Java is once you get
rid of the compile errors, and once you stop triggering NPEs, there
very good chance you have nailed all the bugs.

There are situations where null is expected and it is just a hassle to
explicitly deal with it, and other places where its presence is a sign
of pathology.  

Whatever changes you make to the language should not make you treat
everything the same way.
