Re: [sv-ac] Updated proposal for #1550 - $sampled and sampled value functions

All,

there is another possibility. I think that we should distinguish between 
$sampled and the other functions
$past, $rose, $stable and $fell. For $sampled, there is no meaning in 
treating it like an NBA. For that we can
simply use a reg. So I propose that the $sampled should be updated at 
the prepond region.

Then, $past, $rose, $stable and $fell can be updated in the NBA region 
(as a shortcut for using intermediate regs),
and whenever there is a need for the "prepond view" of these values, one 
can simply nest them inside a $sampled
function.

For example,

the value of $sampled($past(a)) is the same in the active and reactive 
regions.
