I had no idea it was standard. I had heard they had issues with it not being able to handle certain constructs so they were working on getting it to a place it would perform better. Has this changed? I'm not a rust person, but I intend to be. I've barely made it 1/4th way into the book (just started in the past month and I've been busy), but I have a good background in programming and so far it's been super easy. I'm really enjoying how specific the compiler is, and the binary sizes vs Go.
