Yeah, took me a while to spot the difference as well. Let me highlight the relevant lines: > (define mine-two (condition '(mine) '(two))) > ... > (condition-case (thunk) > [ex (mine too) > (format #t "This is a (mine too) condition: ~s~%" ex)] ... > (check (lambda () (signal mine-two))) > (check (lambda () (signal (condition '(mine) '(two))))) Note that in the condition-case you have "mine too", while here it's "mine two". One letter difference :) Cheers, Peter
