    That's definitely my approach when writing a "main" a program,
    there's just no way Lua's gc will be more expensive than the effort
    needed to squeeze performance through micromanaging, most of the
    time.
    
    
    But I've learned to be a bit more careful with heavily used core
    libraries. My stuff runs for a while and consumes a bunch of RAM
    (simulations, graph traversals, and so on). Not hitting the swap may
    be the difference between 10 minutes of runtime and a few hours.
    
    
    Rewriting an internal data structure to allocate smarter, like
    changing an {{x1,y1}, {x2,y2},...} to {x1,x2,...},{y1,y2,...}, can
    make a huge difference in RAM usage and gc costs when you have
    millions of entries and your operations allocate in a tight loop.
