StumpWM has an inconsistency set of exported symbols.  In my module, I
use exported and internal ones.  So it is possible, and sometimes
necessary, to use internal StumpWM symbols within modules.  So it is not
strictly necessary for `defcommand' to export symbols defining new
commands.

There is also no consistence on how modules are written.  Some use
(in-package :stumpwm), so they access all StumpWM symbols and define new
symbols for the StumpWM packages.  Others define separate packages and
hence are affected by symbol visibility, but like I said in the first
paragraph, they might need to access internal symbols anyway.

I am talking from the point of view of a module writer.  Defining new
commands doesn't mean I want to export symbols.  And exporting symbols
inside the macro was surprising and caused a little problem.

Maybe StumpWM should have two `defcommands'?  One for internal use of
StumpWM, which exports symbols, and one for modules, which doesn't?

I am not so sure myself tho.  That is why I asked for the reason for the
exporting in the first place.

Your warning might be related to this, but like I said in a previous
message, my error is triggered when I try to compile a new definition of
`defpackage' after defining some commands in the package.
