Comment:

 Dear thomie, thank you for your comment. Yes, `-interactive-print` is a
 great feature! I regret that I was not able to search out this has been
 done for years.

 There are also several customized `show` function proposed, like `myShow`
 here. However, when I used it in some detail, I found that printing in
 Unicode has many corner cases that are more difficult than it seems ....
 As far as I have searched, I cannot find a unicode-printing function
 that satisfies
 `read . unicode_show == id` for sufficiently many types. For example,
 https://gist.github.com/nushio3/4a10f3c0092295696daf

 Thus, I decided to start a small package `-interactive-print`ing.
 http://hackage.haskell.org/package/unicode-show  I wish this helps many
 people enjoy Haskell!
