[slime-devel] non-interactive interaction with repl

I see how I can non-interactively feed the REPL, by using `slime-repl-eval-string' -- e.g. -- (slime-repl-eval-string "*package*") However, I don't see how to get the back into Emacs in a straightforward way. Whereas the above command prints the current package in the REPL buffer, I desire a command that returns the current package to Emacs. (slime-eval (+ 1 2)) returns 3. (slime-eval '*package*) triggers SLDB with the error The variable SWANK-IO-PACKAGE::*PACKAGE* is unbound. [Condition of type UNBOUND-VARIABLE]
