In the end, I think it comes down to a simple profiling decision.
The question being: Which method is more economical?
If you're handling an event that happens often...like player_death, my guess is
the extra 64
bits ("depending on the compiler") per player might be worth the amount of
function calls if
you're doing it often. It'll certainly prevent sudden choppiness; replacing it
with negligible(?)
sluggishness.
Of course, I base this on absolutely nothing as I haven't profiled the
difference.
