title: Is Haskell an imperative or declarative paradigm?
body: <p>I have read some sources where the Haskell's paradigm is described as <code>functional</code> but <code>imperative</code> paradigm. The main source where this is said is <a href="https://en.wikipedia.org/wiki/Haskell_(programming_language)" rel="nofollow noreferrer">Wikipedia</a>. How is possible a <code>functional</code> and <code>imperative</code> paradigm at the same time, or is this a mistake?  </p>
