Effective Haskell: Left and Right on page 321

Hi Rebecca,

On page 321 you use Left and Right in the function showLeftRight and I think that you should explain explicitly what Left and Right does because it is not obvious to me how they are used to select the type application.

First Post!

I mean, I can see in your example that Left is used to select the first type application, and Right the second one, (I THINK), but I am still unsure.
