描述

the following function has the suggestion included however following the hint results in it not compiling

weirdEq :: (Int, Int) -> (Int, Int) -> Bool
weirdEq (_, 1) (_, 1) = True
weirdEq a b = ((==) `on`) snd a b

Suggestion: Redundant section
Found:
  ((==) `on`) snd
Perhaps:
  (==) `on` snd

v3.3.1 windows and linux

贡献者指南

研究方向: 调查关于 ((==) `on`) snd 的“冗余章节”(redundant section)建议。确定为什么去掉括号会导致编译错误，并提出避免误报的修复方案。
