The reason this matters (to me at least), is that it makes Stefil impossible to use for interactive testing as Stefil expects that: 1. I am interacting with my lisp using slime. 2. It can include swank and a system dependency. I am a little surprised that no one else reported a problem. Matt

No offense, but several people have warned before and after this change that deleting packages behind the user's back is not such a great idea. Perhaps this patch could be reverted until someone figures out a better solution? My two cents. Michael

Signal an error, with a restart to nuke the packages and another to continue with the old ones? Cheers, -- Nikodemus

I disabled the delete-package stuff in the CVS version. Deleting old packages was supposed to avoid confusing error messages, but it is actually more confusing than not to deleting them. There's a new function swank-loader:init &key delete reload which can be called with :delete t to force the deletion. By default it doesn't delete anything. By default, it also doesn't reload swank, if the swank package already exists. Helmut.
