Exploring Scala Stream

stream_exploring.scala

// Looks like a good idea but ...
val toInfinityNBeyond = Stream.continually{1}
// when you abuse it, it can bring ur REPL to a halt 
// and it doesn't do what u think it does anyway so ...
(0 /: toInfinityNBeyond)(_+_)
// you should see ur ALL ur CPUs spike to 100%
// Ctrl+C (kill it)
// If you know how many values to create in the first place, then you can do this ...
val max = 1000
val finiteStreamFromOne = Stream.fill(max)(1)
// again, this expression doesn't do what you think it does as with List[_] because
// all the values are lost except for the last one
(0 /: finiteStreamFromOne)(_+_) 

// To build a stream s.t. each subsequent element is a successor of the previous s.t. 
// successor = previous + 1
val iS = Stream.iterate(1, 99){ _ + 1 }
val result = (0 /: iS)(_ + _) 
// result should read 4950

// One operation i tried to do is to determine whether a finite Seq[_] is present 
// in a infinite Stream[_]. The following expression runs into OutOfMemoryError: Java heap space
