	// * movingAverage(foo,5min) -> the 5min arg will be parsed, so we can request 5min of earlier data, which will affect the request for foo.
	// * consolidateBy(bar, "sum") -> the "sum" arg will be parsed, so we can pass on the fact that bar needs to be sum-consolidated

	// IMPORTANT: for performance and correctness, functions should
	// * not modify slices of points that they get from their inputs
	// * use the pool to get new slices in which to store any new/modified dat
	// * add the newly created slices into the cache so they can be reclaimed after the output is consumed
