Location of getStreamState [it2-bootstrap]

[Deepak S Patwardhan]

Hello,

The following code works in the current lambda implementation (filter
returns Iterable)

Collection<String> names = ...
for (String name : names.filter(s -> s.length() > 10)) {...}

However, it will not work with it2-bootstrap because filter will return
Stream, which is not an Iterable.

Is this just a side-effect of the way Stream API has been (currently)
written OR is it a design goal to discourage external iteration on Stream?

Regards,
Deepak S Patwardhan.

The role of getStreamState is still under discussion.  It may be exposed, or
removed.  Right now it exists only for the implementation, not the API.

Note that StreamOps is not a public class.
