> Memory management is a distraction: Actually, no. I don’t use that many lexical lifetimes and use instead smart pointers. So yes, I have to understand the differences between a Box, an Rc and an Arc, but my productivity is not impacted compared to Node.JS or Go.

By throwing everything on the heap, I doubt you see much improvement performance-wise over Node or Go. You probably even come out behind idiomatic Go which makes good use of the stack. What's the point?
