That's the first thing I thought, too. I'd like to see both Go 1.1 and Go 1.0.3 for a comparison (on this benchmark). I'm hoping that before long we'll be able to count on Go being within a factor of 2 of plain C by most benchmarks.

And I'd like to see CPython 3.3 in addition to PyPy.

But it's quite interesting as is. Thanks.
