Unused variables in Rust are warnings, but in Go they are errors. Warnings are way more pragmatical - you can still get the code to compile when prototyping, but you get a chance to fix them before shipping. Go’s resistance to introduce warnings is ideological, not pragmatical. It makes it more frustrating to use for no benefit elsewhere.
