I started looking at this, and I have a few questions.

1. What is the difference between (debug t) and (debug form body)?  From
my understanding of the manual, there seems to be none.

2. I still don't fully get the `eval-and-compile' stuff.  What exactly
happens when the file is compiled?  I understand that its forms are not
evaluated.  But are the _defmacro_ forms evaluated during compilation?
If not, what happens when the compiler compiles a function containing
a macro invocation?

3. Do I get it correctly that the purpose of the `ignore' calls is to
silence the compiler warnings about `let'ting a variable which is then
not used in the body of `let'?

That's it for now.  Sorry if my questions are elementary - I'm still
struggling with this compilation stuff...

TIA,
