[snip code]

ever heard of the layout-rule?
You must indent the cases for polyArea to exactly the same level as the 
type-declaration, and all declarations in the let-binding to the same level.
Once the indentation is corrected, you get the real error messages -- those 
you should understand easily.

Cheers,
Daniel
