Nuke quick tip: write node with disabled outside of framerange

If you have multiple write nodes in a nuke scene, and want to submit to render all at once, but running on different frame ranges(as their input's framerange), here is a simple expression to put in the write nodes disable knob:
frame < input.first_frame || frame > input.last_frame ? 1 : 0
This way the write node is disabled when current frame is not in the input framgerange. This usually happens to me when converting raw materials for different shots at once.
