Mmm, yes I had thought of that. But I wasn't sure how it would work, as
you can't have variables in the same sense as imperative languages. So
if I create a mainloop sort of function, that passes the old state into
itself, then would I have to modify the output within that fucntion to
get it to display to the user, correct? Thanks for the response!
