The more I learn about this, the more messy it gets :-)

Does CL also allow you to choose lexical or dynamic binding on a
per-file basis?

What kind of binding is used in *scratch* ?

I also wondering how does lexical binding work with the edebugger?
E.g. if I eval the following code with dynamic binding, I can
check the value of x and y using M-: x  and M-: y when the
error happens (z is not bound):
 (let ((x 1) (y 2)) (setq y z))

Can I do the same with lexical binding of x and y?
