I did respect indentation, and here's what I get as an error:

> tutorial.hs:21:23: Illegal type signature: `[Person] people' Perhaps you intended to use -XScopedTypeVariables In a pattern type-signature

You copy-pasted it without a newline.

This is how it should look http://lpaste.net/90921

I guess you have a little error in your code. Maybe if you copied and pasted there was an error.

For example, if you have

     let people :: [Person] people

instead of

     let people :: [Person]
         people = -- ...

that would give you that error.
