Bug #7588: New warnings on ||=

ruby -v: 2.0


I'm now getting warnings on my projects w/ 2.0 (ruby 2.0.0dev (2012-12-08 trunk 38265) [x86_64-darwin12.2.1]) when I use ||= to initialize unset variables. This never happened in < 2.0.

def initialize_test
  self.multiruby_skip ||= []
  self.testlib        ||= :testunit
  self.test_prelude   ||= nil
  self.rspec_dirs     ||= %w(spec lib)
  self.rspec_options  ||= []
end

begets:
