Isn't ok to throw an error if the package doesn't exist?  In any case,
if (in-package "FOO") works, doesn't that mean the package must
already exist?  I guess maybe there's a problem if you're creating the
package in the same file, but that seems like a very easy workaround:
create the package  before using, in a separate file if necessary.  I
think that's considered good practice.

Maxima does this in quite a few places.  It seems to work. Perhaps
we're just lucky?
