Subject: Re: Dealing with nil

Is there really an advantage over the more "traditional" solutions:

x && x.foo
x.foo if x
x || 1
x ? x.foo : 1
x && x.foo || 1

Apart from that I think one should rather deal with nils explicitly
(and maybe a little bit earlier than in your examples).

BTW I personally would rather prefer a statement that throws an error
if an unchecked nil is assigned to a variable. (Which isn't too
difficult to do.[1])

Thomas.
