Ok, what about : int value ?= object.getSubObject().getValue()  : -1; Pros :  - I think the compiler could easily retranscript it using  - Much more readable Cons : - The potential problem is that the "interpretation" differs from an &= or += operator

It's ok for me, in this case.

But did you ever wander why NPE is so common? Isn't that because people do not want write so much if-s and declare so many one time used variables.

but ?: can give something nice: void f(Some some){ ( some.getOut ?: defOut ).write(...); ... }

while ?= would require to: void f(Some some){ OutputStream out ?= some.getOut : defOut; out.write(...); // Now we need worry for 'out' till end of function. ... }
