The only reality is the present moment - state retention is delusion
I do quite a bit of spiritual search in my freetime. And for the longest, I have been bitten by this idea over and over, so now I will express it. And this is not my idea, you can read Eckhart Tolle, "The Power of NOW" or listen to any Advaita Vedanta teacher and they will tell you:
the only thing that is real is the present moment.
your thoughts about the present moment are attempts to conceptualize and relate this moment to other stored concepts and relations. This is what is known as understanding. It is not knowledge, but rather mental comprehension.
Also, Repeatings and recordings via memory are only real when they are brought into the present moment. all of Which means everything which ever happened and everything that ever will happen will happen in the NOW.
So what? Well, Haskell, being a purely functional language is all about NOW. It is one of the few languages which makes a concerted effort to have all statements about past and future effects cleanly, correctly and completely and explicitly described from the standpoint of the Ever Present Presence.
