Figure out data 'visibility' problem in games #4
Description
Solutions:
- Pass only visible things to a function that can only see certain things (i.e. parametrize it more explicitly) - this is the ad-hoc solution.
- Pass the whole data structure, but wrap it in a visibility monad which only exposes certain accessors as defined by the visibility instance definition?
Other issue: you can sometimes see the fact that a list exists and e.g. the top card on a list, but not how many cards are in the list.
In games which transmit data / do IO, we really do need to censor the data defined to be invisible.
