Hello again, Kevin suggested:

I switched to 'Advanced' level because I thought that something was possibly not accepted because it was too difficult. My fault.

There is 'show' function for each data type you write down.

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. > But it's an interesting project. Keep going on it. Don't worry. We just started...
