This and many other things are still likely to change before the Java 8 streams API is complete. Our focus is on making the best long term decisions for Java and not the short term convenience of early adopters (think of yourselves as experimental volunteers).

If you absolutely can't live without the APIs mentioned you need to explain why they are essential and why the alternatives are inadequate/inferior. The minimum I can't absolutely live without is a Turing machine, so don't mind me. It's just that is it the 3rd time that something I really like is removed from the stream API.

Is there a proof that Stream API is Turing complete ?-)

As you might have gathered from the EG discussions, flatMap has not gone away; we've simply removed one of the variants of it. I was talking about FlatMapper.
