I was learning CSV and found this typo in [CSV documents for ruby 2.7.1](https://ruby-doc.org/stdlib-2.7.1/libdoc/csv/rdoc/CSV.html). ```ruby # Headers provided by developer data = CSV.parse('Bob,Engineering,1000', headers: %[name department salary]) data.first.to_h # { "name department salary" => "Bob", nil => "Engineering" } ``` It should be `%w[name department salary]`, I think. This one's too. (`%i[numeric date]`) ```ruby CSV.parse('Bob,2018-03-01,100', converters: %[numeric date]) ```
