There is always a hack for everything, but if you can pass in the + and 
so on to the template then why can you not do this in the model rather 
than the view?

However, you could first pass in the values via other invocations that 
return "" and store them in static variables in your renderer, then 
invoke a format="calculate". Total hack and violation of the idea of 
course, but I suppose that so long as you know this and comment it as 
such, then it is up to you:

$numa;format="storeOp1"$$numb;format="add"$

Or something similar.
