In Zig, function arguments are not wrapped in `.{}`. `.{}` is the syntax for creating a struct or a tuple. This is used as a pattern for allowing optional arguments (options struct) and variadic functions (tuple).

Explicitly discarding return values is a thing many modern programming languages force you to do.

I know, and I don't see unused return values as an error, it should be a warning at best.

And the compiler should be just a bit smarter to avoid the .{} thing when it is not strictly necessary.
