I have to admit it's a little frustrating when you see swift's 
?. syntax notation, it would be a little more practical to be 
able to write

writeln(obj.member?.nested?.val);

Any thoughts?

Use a maybe monad :
Maybe(obj).memeber.nested.val

This doesn't require a language construct. Also, if null check 
are pervasive in your code, you probably have a problem somewhere.
