after running rtest16, how to kill f?



After running just rtest16 (run_testsuite(tests=[rtest16])), both f and p are in the values
list. Oops--how to kill f?

(%i1) f;
incorrect syntax: F is not a prefix operator

(%i1) kill(f);
incorrect syntax: F is not a prefix operator
(%i1) incorrect syntax: Premature termination of input at ;.

(%i1) remarry(f);
incorrect syntax: F is not a prefix operator

(%i1) :lisp(print $f)
#S(MGENARRAY AREF NIL ASET NIL TYPE $FUNCTIONAL NULL NIL GENERATOR
      MFACTORIAL CONTENT #<hash-table 1458fcb0>)
#S(MGENARRAY AREF NIL ASET NIL TYPE $FUNCTIONAL NULL NIL GENERATOR
      MFACTORIAL CONTENT #<hash-table 1458fcb0>)
