@Peilonrayz, the obvious approach would be to use a separate Boolean variable. An alternative, which I consider hackier, would be to not have a separate variable for internal_state at all: result = function(); function = lambda () => result; return result

My function never return None, but in the general case I guess that you would just have a boolean marker beside the internal_state, so you can tell if the function has been evaluated or not, but that's just a guess and probably not the best solution either. Concerning the cache solution I'll have a look at it.

So how do you change the code with regard to the first point if None is a valid return?
