Yes. That package is a good example because it portrays how often it works
and how often it doesn't.
I personally find these small issues completely worth the overall beauty of
the code, but that's entirely a matter of preference.

FWIW, Both issues are workaroundable (I'm guessing that's not a word :-)).

This will be the case for any namespacing solution. You can work around by
defining the minor mode after the macro.
Also, I would be happy to add an option to avoid namespacing the
`define-minor-mode' form (and similar ones), if anyone wants it.

This can also be worked around by defining the keymap with a series of
`define-key' statements instead of doing it inside the `define-minor-mode'.
Which is something I see a lot of packages doing anyway.

Now that I think about it, I can also improve the macro to "look inside"
the fifth argument of a `define-minor-mode' call even if it's a quoted
list, since that argument is guaranteed to be a keymap.
