While I would use &method(:puts), it honestly never occurred to me, and it 
seems like a clever hack. It also only solves that one problem, and not, say:

names.map{|name| name.split.last}

I suppose I could do this instead, but it doesn't save any typing and results 
in an extra intermediate array being constructed:

names.map(&:split).map(&:last)

I'm sure I'm missing something, though.
