It seems like this might be a better syntax. 

function foo(sequence this, integer update_value)  
    integer prior_value = this[1]  
    this[1] = update_value  
    return (2){this, prior_value} 
end function

It can be read aloud as "return two values, this and prior_value."

Unfortunately the (round brackets) make it unnecessarily hard, since return (2) is a valid statement (and {this,prior} could be the start of a multiple assignment).

Just after you posted I suggested return[2] or return[2..8] (which could be read as "return at least two and at most eight values"), but I'll accept you pipped me to it.
