GitHub user ataylor284 opened a pull request:
https://github.com/apache/groovy/pull/247
Added new class BufferedIterator.
BufferedIterator is a wrapper for Iterator that adds a new method
`head` to return the next item without consuming it. A helper method
was also added to DefaultGroovyMethods to create a buffered wrapper by
calling iterator.buffered() on any Iterator. BufferedIterator is
loosely based on the Scala class of the same name.
