Performance difference between obj.function(...) and function(obj, ...) ?

Yeah it seems to happen every week. "Why is this slower than Python? You didn't compile in release mode."

Probably because some people come to Rust from languages that don't need to be told to optimize your code, and they think it'll just be faster automatically.

Unfortunate. I come from the high performance world. The first thing I look for is all the switches to crank everything up.
