It's also possible to write C code that makes extensive use of goto. :)

To be fair, ACPI bytecode for actual hardware may need to rely on the
firmware because of limitations in the hardware. But I think qemu is
one instance where any ACPI bytecode can be kept simple.

Where is that code? Who has the ASL for qemu? Who wrote it? Is it big?
