Re: macro returning more than one form

What is the best way to write a macro that returns more than one form to the top level? E.g.

(in-package :xxx) (defun ...)

I've been wrapping a progn around the result, but LW doesn't like it very much, and SBCL seems to hate it.

That's a pretty good question. I've never been able to find a way. It feels like it might go against some kind of fundamental principle of macros.

What does LW and SBCL hate about wrapping toplevel forms in progn?
