Bug #8224: defined?(()) and defined? () are inconsistent

• Status: Closed
• Assignee: -
• Target version: -
• ruby -v: ruby 2.1.0dev (2013-04-05 trunk 40128) [x86_64-darwin11.4.0]

=begin
(({defined?(())})) and (({defined? ()})) return different values.

I would there to be no difference between (({defined? })) and (({defined?()})), except for precedence.

Example:

defined?( () ) # => "expression"
defined?  ()   # => "nil"

=end

parse.y: "nil" for defined? with empty expression

• parse.y (new_defined): remove all extra parentheses, and return
  "nil" for defined? with empty expression.
