Hi,<div>    I&#39;m reading &quot;Learn You a Haskell...&quot; and have a question about the chapter &quot;Making Our Own Types and Typeclasses&quot;. On the &#39;Functor&#39;/&#39;Either&#39; example, I feel completely lost. I don&#39;t see why the &#39;Left x&#39; portion of &#39;Functor (Either a)&#39; is simply &#39;Left x&#39; and the document is not exactly clear. Any clarification would be most appreciated.</div>
<div><br></div><div>Sincerely,</div><div>Frank D. Martinez</div><br><br>-- <br>P.S.: I prefer to be reached on BitMessage at BM-2D8txNiU7b84d2tgqvJQdgBog6A69oDAx6<br>
