Subject: using "if 3 in list_foo" for Python for Ruby

There is no such thing as

  if 3 in [3, 2, 1]

construct in Ruby?  so the common way in Ruby is

  if list1.include?(3)

or

  if list1.index(3)

is that right?  is there an idiom in Ruby to do something like

  if 3.in([3,2,1])

or

  if 3.in [3,2,1]
