architecture (VMState). Right now, VMState lacks type safety because
it is hard to place the ``VMStateField`` definitions in traits.
* NUL-terminated file names with ``#[track_caller]`` are scheduled for
inclusion as ``#![feature(location_file_nul)]``, but it will be a while
before QEMU can use them. For now, there is special code in
``util/error.c`` to support non-NUL-terminated file names.
* associated const equality would be nice to have for some users of
``callbacks::FnCall``, but is still experimental. ``ASSERT_IS_SOME``
replaces it.
