One of the features in go that makes it workable is you can assign it away via: _ = somevar

That eliminates the unused chain problem. Not sure if zig included that part of the feature as well.

Generally I agree though. The main problem with forcing unused variables, imo, is that it forces you to think a certain way. When I'm exploring the solution space on something, those constraints feel inhibiting.

> you can assign it away via: _ = somevar

If one suggested this in any other language to suppress "unused variable" warnings it would be considered a lazy way to avoid fixing the issue.

Meanwhile the developer of Zig himself recommended doing this[0] which only shows what a bad idea it is to make this a compiler error imho. It encourages workarounds and enforces something we automated long ago in the form of dead code elimination.
