描述

There is a proposal to modify elm-compiler to allow trailing commas in tuples, lists and records. If implemented, the official elm style guide will likely change to prefer trailing commas instead of leading commas, and to always add the optional final comma.

研究方向
Investigate the elm format source code to understand the current formatting logic for lists, tuples, and records. Examine the Elm parser (likely in elm compiler) to see how trailing commas are currently handled. Discuss with maintainers the decision on whether to adopt trailing commas and the preferred style. Implement changes in elm format to optionally allow and format trailing commas as per the style guide.
