This is a working document. It is badly written, badly structured, far from completion and may contain inaccurate informations. You should read it with care.
I have some special tags inlined you should more or less ignore:
| Notation example | Description |
| <type> | represent a scheme object of family type |
| define | represent a name in the scheme name space |
| expr | represent some kind of scheme object or list. May have some sinful meaning |
