No, I'm saying I could put up with

for(;;)
{
fetch_microwave_command(&foo);
execute_microwave_command(&foo);
}

because it's quite evident that this is a genuinely "infinite" loop, in the
limited sense of that word applicable to a microwave oven!

All else being equal, yes...

....and yes.

(This reply is purely for clarification of my earlier intent - I did read
the rest of your article, and I accept that our viewpoints differ.)
