Also: in looking around I find that every
official webpage/document about this that
shows examples shows functions with no
arguments. (But none that I found has any
explicit words about the argument list
requirements. None say that the arguments
are the same as for any standard variation
for how main can be declared.)

For a stack architecture, there would be stack
pushes set up before the calls and pops set
up after the calls. In architectures with
some degree of register-based argument passing
it is harder to see what has a
garbage-in/garbage-out/accidental status vs.
what is deliberate.

It looks to me like the existing documentation
could stand an update about parameters and
arguments.
