Well, weird benchmarks are probably all those where your favorite language doesn't look good ;-)

I would say in this case what's 'weird' about the benchmarks is that the optimization strategy taken across the languages is incredibly uneven. Indeed, simply wrapping the above julia code in a `let` block so it's not out in the global scope is sufficient to have it on par with C++ (assuming the same flags are used, e.g. fastmath).
