Three questions about Slime and the repl:
1. In the repl, how do you say "undefine everything defined so far" so
you can reload a file without getting a bunch of "already defined" messages?
2. Inside the file you're loading, how do you say "stop reading and
close this file" so you can go back to the repl and debug everything up
to that point without having to comment out everything after that?
3. In Slime, C-c C-m isn't working. It just echoes the macro name, it
doesn't echo any expansion. What's the magic word that makes it work?

The only perfect way is
CL-USER> (quit)
M-X slime
This gives you a completely new lisp session. Note that doing so
doesn't lose your history or close any buffers.

Insert an (abort) at the point where you want execution to halt.

Are you placing the cursor (point) on the closing parenthesis for the
entire macro expression before pressing C-c C-m ?

Someone posted a ",rest" shortcut a while ago. If you type that in the
REPL, Slime will restart underlying Lisp.

Hmm, I tend to put the cursor at the opening parenthesis. I think that's
where you end up after pressing C-M-u.

Is (quit) supposed to stop the repl in Slime?
It says "Evaluation aborted", but sbcl keeps running.
Also, this question is about the regular repl without Slime.

Thank you, that seems to work.

No, I wasn't.

That's much easier.

This is pretty tricky to do. Generally, you're better off just
restarting the image. In SLIME, this is done with
,restart-inferior-lisp . At the "regular REPL", just (quit) and then
start again.
It is sometimes possible to get this behavior by deleting packages.
For instance, if you loaded packages called FOO and BAR, calling
(delete-package "FOO") will make all of its symbols eligible for
garbage collection and now you can reload whatever code defines the
functions and variables in FOO. If you have other packages that are
using FOO, though, this could cause problems.
Although this is a common question here, the need for this doesn't
actually come up very often. If you're using ASDF, just restart your
Lisp image and reload the ASDF system you're working on and you should
be mostly back where you started. If that's not enough, just restart
the image.

Are you sure the form is a macro? Can you post the text of the form?

In Slime, how do you expand a macro defined by MACROLET?
The function containing it isn't compiling,
and the error is somewhere in the macro.

I'm not aware of any way of doing this, but you can certainly move it
out into a DEFMACRO to test it out and then put it back where it came
from.
For this very reason (i.e. the difficulty of debugging), I prefer
DEFMACRO to MACROLET except for very, very simple macros.

Use slime-macroexpand-all (C-C M-M). For example with:
(defun foo (z)
(macrolet ((a (x)
`(print ,x)))
(macrolet ((b (x)
`(a (1+ ,x))))
(b (a z)))))
Put the point on the opening paren before the first MACROLET. Then C-C
M-M, and the macroexpansion buffer should pop up with:
(MACROLET ((A (X)
`(PRINT ,X)))
(MACROLET ((B (X)
`(A (1+ ,X))))
(PRINT (1+ (PRINT Z)))))

Switch to SLIME REPL, type `,' (single comma) and type command
restart-inferior-lisp RET

Move cursor to proper position
