Question on usage of Stream
Hello,
The following simple example illustrates the usage of streams in the documentation of Stream.scala:
> def from(n: Int): Stream[Int] = Stream.cons(n, from(n + 1))
It looks very simple but the problem is that obviously the method is not tail recursive and if I do:
> from(2) take 3715 print
I get a java.lang.StackOverflowError
This shows that building infinite streams this way is quite limited :)
But is there a better way?
Thanks,
Sébastien
