// AcyclicTransformer returns a [cmp.Transformer] with a filter applied that ensures
// that the transformer cannot be recursively applied upon its own output.
//
// An example use case is a transformer that splits a string by lines:
//
//	AcyclicTransformer("SplitLines", func(s string) []string{
//		return strings.Split(s, "\n")
//	})
//
// Had this been an unfiltered [cmp.Transformer] instead, this would result in an
// infinite cycle converting a string to []string to [][]string and so on.
