Anyway, what could possibly happen at the end of a while loop, besides going back to the begining for the test?

Besides, if you have a bug in your code, you will have to look at the whole block anyway.

That's indeed tricky: if there's a for loop inside the guarded block which generates many defers, a stack would have to be created to handle them somehow.

Option types can be nested, nullable types cannot.
