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

class Foo
  def bar
    :barzzz
  end
end
foo = Foo.new

foo.bar
# => :barzzz
foo&.bar
# => :barzzz
