Hi @sanjoy @wmi @hfinkel, is there any discussion ongoing about this patch? There is more than month without progress, should we maybe start a discussion here?

I'm personaly also inclined to think that this caching logic is wrong and we should get rid of it, but will clearly have consequences from compile time point, so it's definitely worth discussing.
