I find this kind of odd.

  $ ruby -w
  puts([1,2,3].include? 1)
  -:1: warning: parenthesize argument(s) for future version
  true

Surely there's no ambiguity in that expression.  What principle is at work
here?

Sorry if this is similar to other cases already discussed.  I was paying
attention, but those cases seemed more ambiguous, hence the warning.
