In my verilog test programs, I currently use $finish_and_return(1) to
indicate failure to the test driver script. If that can be replaced with
$fatal (which I take is more standard?), that would be nice.

How do other simulators implement $fatal? If Icarus departs from
conventions by returning EXIT_FAILURE, then I would better stay with
$finish_and_return(1) which will fail in a more obvious way if not using
Icarus.
