Main targeting - passing two and more arguments, mainly "instance, key" sequences. Much function don't uses array value directly, but passing these pairs (may have different reasons). Mostly these indexes may constant, so just simply bake array/object reference and index into one interface, and operate like simple variables, or passing to function through spreads. Also, I forgot to press "Reply to All".
