Regarding implicit context, it could be nice to use it for time. Games often have different parts running with different speeds, during for example a slowdown effect, or pause, when the game simulation runs slower but the UI should still run at normal speed. They run in different time contexts. You could be passing a time struct around, but slapping it into the context is tempting.
