Evaluating expressions in SLIME while using STEP

I am using SLIME with SBCL. Normally in SBCL, I can do (step (call-some-function 1 2 3)) and I will be able to step through/into/out of each line of code, as well as executing arbitrary expressions of my own to see what the current state of certain variables are.

But if I try to do the same in the REPL in SLIME, I get:

Evaluating call:
  (CP-GET-ALL-PE-MATCHES-ANY-LENGTH SENT-ID)
With arguments:
  581869302


   [Condition of type STEP-FORM-CONDITION]

Restarts:
 0: [STEP-CONTINUE] Resume normal execution
 1: [STEP-OUT] Resume stepping after returning from this function
 2: [STEP-NEXT] Step over call
 3: [STEP-INTO] Step into call
 4: [ABORT] Exit debugger, returning to top level.

Backtrace:
  0: (call-some-function 1 2 3)
  ...

There doesn't seem to be any way to obtain the current value of sent-id, or to evaluate (nth 1 some-list).

Is this in fact the case, and if so, does that mean I will have to fire up a second instance of SBCL in the terminal, and step through the function at the same time as in SLIME in order to get this functionality?

You can still use the REPL in SLIME when placed in the debugger, I routinely do this e.g. when errors occur. You just have to switch to the REPL buffer and type. It does not show a prompt initially, but it does once you give it an initial form.
