Hi all,

Please review and comment on this proposal to allow Stream instances to be used in enhanced-for ("for-each") loops.

Abstract

Occasionally it's useful to iterate a Stream using a conventional loop. However, the Stream interface doesn't implement Iterable, and therefore streams cannot be used with the enhanced-for statement. This is a proposal to remedy that situation by introducing a new interface IterableOnce that is a subtype of Iterable, and then retrofitting the Stream interface to implement it. Other JDK classes will also be retrofitted to implement IterableOnce.

Full Proposal:

Bug report:

    https://bugs.openjdk.java.net/browse/JDK-8148917

Webrev:

Note, this changeset isn't ready to push yet. In particular, it has no tests yet. However, the implementation is so simple that I figured I should include it. Comments on the specification wording are also welcome.

Thanks,

s'marks
