The original test implementation for the react test via #29 was specifying multiple constructors in order to specify different lambda parameter counts which allowed for a test to be written like: reactor.ComputeCell(one, two) { x, y -> x + y * 10 }. The multiple constructor approach was ditched in favor of a single constructor but taking in a list into a lambda expression which resulted in a test of: reactor.ComputeCell(one, two) { it[0] + it[1] * 10 }

Now that Kotlin 1.1 has come out (#38) we can provide a similar test syntax originally provided by using the new lambda destructuring capability to provide a test of: reactor.ComputeCell(one, two) { (x, y) -> x + y * 10 }.
