2 years ago Thank you for taking the time to submit a pull request. In this case, these extra commas aren't typos. Starting in Ruby 1.9, you can use trailing commas in method calls (and other places), even if nothing follows them. Trailing commas are often used in code like this (one argument per line), because when adding arguments, you don't need to modify an existing line.
