def making_declared_methods_public
  # Our home-grown instance_exec in ruby 1.8.6 results in any methods
  # declared in the block eval'd by instance_exec in the block to which we
  # are yielding here are scoped private. This is NOT the case for Ruby
  # 1.8.7 or 1.9.
  #
  # Also, due some crazy scoping that I don't understand, these methods
  # are actually available in the specs (something about the matcher being
  # defined in the scope of RSpec::Matchers or within an example), so not
  # doing the following will not cause specs to fail, but they *will*
  # cause features to fail and that will make users unhappy. So don't.
