Ruby try shortcut - Safe Navigation Operator

Today I learned that ruby (2.3.0) has an operator called Safe Navigation &. and this is like a short cut for that Rails try method:

foo = nil
# NoMethodError: undefined method `bar` for nil:NilClass
# 	from (irb):18
# => nil

class Foo
  def bar
foo =
# => :barzzz
# => :barzzz
