[Haskell-beginners] Writing a Parser with attoparsec that reads from a list of tokens

The thing is you can write parsers for tokens, then write parsers that
consume those tokens by exclusively using the token parsers as the building
blocks rather than the raw steam, all using the same combinators and
mechanisms. This is much more flexible.
