This thread made me look up NilClass in the docs.  I learned something new.
& is a method of nil, which always returns false.
nil & return(something)

I often do:
puts "error" or exit if condition
which reads a little funny, but it works and is concise.
(I hate reading code where the error handling takes up way more space than
the essential logic)
