Have you done ex. 3: The words function counts the number of words in a
string. Modify the WC.hs example to count the number of words in a file. ?
Originally, WC uses lines to break a String into a list of lines.
Then you use words to break a String into a list of words.
Now you want to make a list of characters out of the String.
How do you do that again?
