CL-USER(18): (cl-user::hemlock) debugger invoked on condition of type SIMPLE-ERROR in thread 1427: Hemlock variables must be in the "HEMLOCK" package, but HEMLOCK-INTERNALS:DEFAULT-FONT is in the "HEMLOCK-INTERNALS" package. Within the debugger, you can type HELP for help. At any command prompt (within the debugger or not) you can type (SB-EXT:QUIT) to terminate the SBCL executable. The condition which caused the debugger to be entered is bound to *DEBUG-CONDITION*. You can suppress this message by clearing *DEBUG-BEGINNER-HELP-P*. restarts (invokable by number or by possibly-abbreviated name): 0: [ABORT ] Reduce debugger level (leaving debugger, returning to toplevel). 1: [TOPLEVEL] Restart at toplevel READ/EVAL/PRINT loop. (HEMLOCK-INTERNALS::UNDEFINED-VARIABLE-ERROR HEMLOCK-INTERNALS:DEFAULT-FONT)
