                    Hi internals,
I've been following the resolution of this bug:
https://bugs.php.net/bug.php?id=44392
and it seems that there is no safe way to expose the internal 
SplFileObject filepointer.
So I was wondering if we could not do things differently and instead of 
trying to expose the internal file pointer make any stream_* function 
which accept a resource stream as parameter accept a SplFileObject. By 
doing so we could resolve a couple of issues I encountered while using this 
SPL object without adding any new method to the class we could:
- get informations about the object seekable and open mode status using 
stream_get_meta_data. - append/prepend stream filters without using the 
php://filter/hack
which has its own limitations. 
What do you think ?
