On my remote slime, (slime-eval (list 'swank:eval-and-grab-output (format "%s" '*package*))) returns: ("" "#<PACKAGE \"COMMON-LISP-USER\">") and on my local slime, it returns: ("" "#<PACKAGE \"ELEPHANT-USER\">") But in both cases, I am in the :elephant-user package on the REPL. What's the story? I thought that the combo of functions used here was always going to evaluate its arguments on the same thread that is used in the REPL?
