So your ice turns 'let unused = func();' into 'let _ = func();' automatically? Okay but then do I later have to grep for 'let _' to find all these unused variables and delete them? This is silly and a has consequence of zig not having any system for warnings

Why not ignore unused variables in debug and warn in release mode?

Warning everywhere makes sense. BMG zig doesn't have warnings at all. Just errors

as a fan of him this rationale did not make a shred of sense

"Both parties can have their preference" - this was already true of C where you can just turn enable unused variable warnings or turn them into hard errors, this has nothing to do with the decision.

I also don't want my lsp randomly rewriting my code (???)

Very nice interview. The clarity with which Andrew Kelly speaks is refreshing.
