Hi Juncheng,
I think for learning "code", as in writing nice code, get yourself the Hlinter
[1] running.
It really spots great improvements and some very haskelly ways.
For Learning purposes I would suggest that you first "try it your way" step by
step, and check every step with hlint.
So: fun1 -> Hlint -> fun2 -> Hlint
Additionally you might want to enable a spell-checker (like, a normal one, for
english).
Last thing you might find very useful is a local Hoogle [2] install.
It's amazingly convenient if you want to know, e.g. the function which gives a
length of a list, but you don't remember if it was len, length, size, count ...
So you just search for [a] -> Int and voila.
Second Hoogle can help you find similar functions to what you are currently
building, often you are implementing something that is somewhere as a higher
order function already.
best regards,
Leonhard
