Very important feature that. I usually choose my language based on such important considerations. Busy deleting my Scala code as I write this and rewriting it into Java code 5-10 times the size so I don't have to suffer from being confused between null and None. Something in the back of my head tells me it has something to do with the infamous null pointer exception...
I'm not confused between null and None. That's obvious and wholly pointless.
You should know that you must initialise all types to a default value. Then you don't need a language feature for "None". Being lazy or stupid is not a reason to add a language feature.
Oh and none of my code has thrown an NPE for over 10 years. That was when I started using pre and post condition checking which ultimately solves a lot more problems than some language feature.
There is nowt wrong with null, if you truly understand what it is.
That's a lot like arguing that since my C++ code hasn't segfaulted or leaked memory in 10 years that garbage collection in Java is essentially pointless. I also don't see much need for classes in that new-fangled C++ thing since my assembler code has a "solid" feel to it and has worked reliably for years. Being too lazy to initialize registers correctly is not a reason to add more features.
It still feels "solid" and dependable and without much fluff.
