Issue #19567 has been updated by ko1 (Koichi Sasada). why not `, or` too? ---------------------------------------- Feature #19567: Add Oxford Comma Support for better readability https://bugs.ruby-lang.org/issues/19567#change-102607 * Author: tenderlovemaking (Aaron Patterson) * Status: Open * Priority: Normal ---------------------------------------- Ruby has regular commas: ```ruby [a, b, c] ``` Ruby has trailing commas: ```ruby [ a, b, c, ] ``` But I think both of these are hard to read compared to the Oxford comma. We should introduce the Oxford comma so that code is easier to read: For example: ```ruby def foo a, b, and c [a, b, and c] end p foo(1, 2, and 3) ``` As an added bonus, this feature also makes specifying musical beats quite natural, for example: ``` [1, and 2, and 3, and 4] ``` Just to make sure that everyone is pleased, you are allowed to mix the Oxford comma with trailing commas like this: ``` [ 1, and 2, and 3, and 4, ] ``` ---Files-------------------------------- 0001-Add-Oxford-Comma-support.patch (2.09 KB) -- https://bugs.ruby-lang.org/
