Note that this was 3 years ago, so there have been GC 
improvements since then. I'm not sure what the results would be 
like today (or what the code is like in terms of needless 
allocations).

That being said, you probably want to avoid the GC as much as 
possible for games. Luckily we have tools like -vgc to help with 
that now (and @nogc, but I still consider this mostly unusable 
thanks largely to exceptions).
