i did not mention [atan2] and [clip] in my arguing for good reasons...

i agree that [clip] should respond to bang.
i am not that sure about [atan2]: personally i think that atan2 is a
unop (the values are just there for get all 4 quadrants) and the 2nd
inlet shouldn't be there at all.

as for getting the last result, why not use a [f] _after_ the object?
this way you don't have to retrigger the "costy" operation.
