It is kind of disappointing to see that... BMP (a.k.a. the Microsoft DIB) is preferred as the "debug" format, while there are way simpler formats, specifically _designed_ for simplicity, debuggability…

It has occurred to me that a `Node (Elem a)` is wasting quite a bit of space, since it stores an `Int` as well as the three pointers to `newtype`s. The `newtype` noise is often distracting as well. It…

比如：Maybe Int
二元运算符：是什么？
单位元：又是什么？
二元运算运算对象：是什么？
运算符的运算对象就不同类型，一个是包装了函数，另一个包装了数值，单位元：又是什么？

In the wake of the [exact-printer](https://github.com/haskell/cabal/issues/7544) initiative, [I proposed another approach](https://twitter.com/Profpatsch/status/1426523345730908161): why not say good …
