What do you base that statistic on? I'm not arguing that fact, just that I
haven't seen any evidence one way or the other. What causes Go to create
significantly more garbage than D? Are there benchmarks or test cases I
should be aware of on the topic?
I'm quite curious to know more about this stuff, but I haven't found that
many comparisons between languages (in particular, C# would be of most
interest to me, since most game devs are most familiar with that)
