Ch.9, be_named matcher should use "=="

[JunichiIto]

In be_named matcher, eq is used but it fails with message "ArgumentError: wrong number of arguments (1 for 0)". According to the RSpec document, it should be "==".

RSpec::Matchers.define :be_named do |expected|
  match do |actual|
    # not work
    # actual.name eq expected 

    # should be
    actual.name == expected
  end
  description do
    "return a full name as a string"
  end
end
