I could live with that, but I'd prefer my suggestion because it wouldn't 
require the creation of an extra label for what's essentially the same 
variable. With your code we'd just end up with a whole bunch of:

Foo? myObj = ...;
if (Foo nonnullMyObj = myObj) //etc...

// or

Foo? nullableMyObj = ...;
if (Foo myObj = nullableMyObj) //etc...

...Which just seems unnecessary to me.
