1) Programming is rather limiting.

2) "The cheapest, fastest, and more reliable components of a system are
those that aren't there." Or, as Asko pointed out, "Every additional
feature also adds to the learning curve, documentation pages, etc.
etc.".

3) When we stop asking for new features, we have more time (and
motivation) to realize how to implement them.

(I leave this "automatic post-GC function" as an exercise. Hints:
* "automatic post-GC function" -> gc metamethod
* "current memory info" -> lua_getgcthreshold/count"
* "returns the new desired threshold" -> lua_setgcthreshold
)
