Other documentation ideas: cheatsheet/table + gentle tutorial

[akeep]

Tim Zakian is working on a gentle tutorial document.

Another thing I'd like to put together would be a little cheatsheet in the form of a table or spreadsheet that shows:

• which forms bind which names
• which forms expect which names

Anything else that should go in there?

One thing I'm wondering about is how we can best clarify to students where the magic ends and the plain ol' Scheme code begins.
