Tobias, I started looking into your new version of the arglist code and came across this bug: In the REPL, I type (eval-when M-x slime-complete-form RET. This drops me into sldb: invalid number of arguments: 1 [Condition of type SB-INT:SIMPLE-PROGRAM-ERROR] Restarts: 0: [ABORT] Return to SLIME's top level. 1: [TERMINATE-THREAD] Terminate this thread (#<THREAD "repl-thread" {B4D9C81}>) Backtrace: 0: (SWANK::REMOVE-ACTUAL-ARGS #S(SWANK-BACKEND:ARGLIST :PROVIDED-ARGS NIL :REQUIRED-ARGS (#S(SWANK-BACKEND:ARGLIST :PROVIDED-ARGS NIL :REQUIRED-ARGS NIL :OPTIONAL-ARGS NIL :KEY-P NIL :KEYWORD-ARGS NIL :REST NIL ..)))) 1: (SWANK:COMPLETE-FORM ("eval-when")) ...
