# spec/support/shared_subject.rb

module RSpecSharedSubjectMacros

  # Usage:
  # 1. Replace 'subject' with 'shared_subject' to share the first result acroos the whole context
  # 2. (optional) replace 'before(:each)' blocks with 'shared_setup'
  # 3. Done. The subject will be shared within one, single context (nested will be re-setup again)
  #
  # DANGER NOTE: Make sure you accept the disadvantages of this, such as:
