As for code size cost, 1 function call before a return statement is no big deal. Even so,
I have <a href="https://github.com/ziglang/zig/issues/690">a plan</a> to make the call to
{#syntax#}__zig_return_error.{#endsyntax#} a tail call, which brings the code size cost down to actually zero. What is a return statement in code without error return tracing can become a jump instruction in code with error return tracing.
