Any pattern&practise here for documentation in Haskell?
Are there anything as elegant/handy as what Python does below?

Help on built-in function count:

推荐答案

目前，没有办法在ghci内查看Haddock文档，但是有一张机票a>。

Currently, there is no way to view the Haddock documentation within ghci, but there is a ticket for it.

然而，您可以使用：info 命令获取一小部分信息，例如

You can however get a small bit of info using the :info command, e.g.

ghci> :i nub
nub :: (Eq a) => [a] -> [a]     -- Defined in Data.List  

，以便您至少知道在哪里寻找特定功能的文档。

so that you at least know where to look for the documentation for a particular function.
