I don't believe we need spam?.eggs.cheese?.aardvark, because I don't 
think it is justified by the small benefits it gets us.
For the same reason, I don't believe we need spam.eggs.cheese.aardvark? 
(there is exactly the same number of use cases). We win a bit in 
readability as it's closer to most spoken languages, but we lose in 
granularity as we're hiding any error that would raise if spam.eggs 
returned None, so it's not a full win on this side either...
