[OT] my experience with nullable types (C#)

[Python]

BTW, NET10 will have a new operator, the null check assignment:


`someRef?.Prop = 10` will be shorthand for:

```
if (someRef != null)
   someRef.Prop = 10;
```

But the nice part is that if through flow analysis the compiler 
will know that someRef is not null, it will strip out the null 
check.
