Help us understand the problem. What is going on with this article?

GHCiを起動したときに、定義しておいた関数などを自動ロードする

~/.ghci
:load ~/.ghci.hs
~/.ghci.hs
module Preset where

import Prelude

xs :: [Int]
xs = [1 .. 10]

GHCiを起動

>>> xs
[1,2,3,4,5,6,7,8,9,10]

やったね!

NOTICE

(グローバルプロジェクトでない)haskell-stackプロジェクト内で stack ghci すると、プロジェクト内のモジュールのみがロードされるので、手動で >>> import Preset してあげる必要があるようです。
(もちろん :module +Preset でもおっけー!)

なんで……?? 🤔
