I meant `C-x C-e' (although I would have said `M-C-x').

Usually when I'm developing an Emacs Lisp package that's simple enough
to fit in a single file, I will load the whole thing in interpreted
mode (typically by loading the file and using M-x
eval-current-buffer).  At this point, I know that no macros I defined
in this file are used by a byte-compiled function, so I can safely
redefine macros.  (Of course, things would be different if the package
were sufficiently performance-critical that parts needed to be
byte-compiled even during development.)
