I find it perfectly natural that the 'name'

you to have expression where somewhere in the path is a null. The end
result is just null.
Exactly!
I introduced the term "failing gracefully" before. That was a mistake.
It's not at all what's about. It's about what is logical and what isn't.
get: It's pefectly logical to return null
set: Can't be done - throw an exception
