Because the language does not enforce the restriction that the return value should be a callable. If it's not a callable, then the result will just be that something non-callable is bound to the "roll_die" name -- which could be useful, but is probably a bad idea in general. > And why, if I remove the decorator and just > leave the two functions as if, does the call to move(roll_die()) work? > Isn't that what the decorator syntax is essentially doing? No. The decorator syntax is doing: roll_die = move(roll_die) If you then call roll_die, that is equivalent to "move(roll_die)()", which is not the same thing as "move(roll_die())".
