create-swank-server's API is currently:
(create-swank-server &optional port style announce-fn dont-close external-format)
i'm not too keen on all those &optional arg (especially since i often like to set dont-close to T and leave pert, style and announce-fn as tehir defalut values). no i'd like to change the API to this:
(create-swank-server &optional port &key style announce-fn dont-close external-format) ^^^^
as this would be an incompatable change i'd like to know who's using create-swank-server outside of slime and what they think about this change.
