[OT] Teaching Haskell in High School

Hello again,

You're right. That makes the messages much better. I switched to 'Advanced'
level because I thought that something was possibly not accepted because it
was too difficult. My fault.

We certainly do. They don't seem to mind; I even feel that they think it's
nice to help research.

There is 'show' function for each data type you write down. Eq and Ord are
not generated but we will do that; we will need it anyway for our simple
class system.

I don't know. Could be. We'll probably provide two different Preludes, one
with and one without overloading. This would compare to the language levels
in DrScheme. A lot is possible in this area.

Don't worry. We just started...
