I can only find anything like that in revision well before even 3.5.
There used to be a version with "Actual1" and "Actual2" as well so I
think it's probably just the (lone) function argument to pass. As in,
"I'm creating a call instruction for a function with some prototype,
and here's the actual argument I want passed".

Cheers.
