I write a lot of GO? Do you think I'm unaware of its warts? Do you think I'm not sick of typing err != nil? Do you think I dont sometimes cut corners and NOT deal with that error on the spot or just _ it cause it's a throw away chunk of code?

Pick a language, any one, and there's probably a post by someone complaining about a bad design decision or a wart on its fuzzy ass... Nothing is perfect.

Yes go has flaws... I find that first class, high speed, testing makes the fact that I screw these things up all the time moot. Test, fix move on to the next project.
