yes, but I was curious about doing that during a debug session. Attempting to set! a procedure to a lambda results in: application: not a procedure; expected a procedure that can be applied to arguments given: '(lambda (x) (..)) arguments...: ... so the 'New value for f' dialog input is interpreted as text, not a lambda expression. no biggie - was just curious if this was possible at all. could be nice, though, to be able to temporarily change behaviors during a debug session in this manner (e.g., for stubbing purposes)
