Hello,
I'm currently working on some extensions to slime (I hope to release the source at end of the month) and I've found some minor problems.
Currently the 'slime-repl-stack-package' is not initialized with M-x slime (only with slime-start-and-load, AFAIK), none the less the repl starts with the CL-USER package. Shouldn't the stack be initialized with that package?
The other problem is only a matter of consistency. The slime-simple-completions doesn't have the same interface of slime-completions. I think there are some problems with the handling of CL symbols and packages, but I'll comment on that later.
Continue with the great job. :)
