TextIterator does not implement Iterator interface, only Traversable.
It just happens to have functions of the same name as Iterator.

I am working on implementing BreakIterator API [1]. I considered two
approaches: making a separate class or merging the API into the

cleaner, but I can see people wanting to use it in foreach(), and
since TextIterator already provides a lot of BreakIterator's
functionality, I decided that merging would be the best option.
However, there is an overlap between the BreakIterator API and the
current TextIterator one, so there will have to be some changes.
1. TextIterator::current() signature will change from:
mixed current()
to:
mixed current(integer &$offset)
This will raise the same issue as we have/had with the reflection API:
[EMAIL PROTECTED]:~/build/php-unicode-debug$ cli -r 'interface
i{function f();} class c implements i{function f($a){}}'
Fatal error: Declaration of c::f() must be compatible with that of
i::f() in Command line code on line 1
Nah, don't look at me--I don't like that either.
3. TextIterator::rewind() will be renamed to TextIterator::first() to
conform to BreakIterator's first()/last() API.
So this is heads up. Let me know if you have a problem with this.
Huh? Rename or alias? It can't implement Iterator if there's no
rewind() method.
