- MFH Fixed Bug #34590 User defined PDOStatement class can't implement

  methods
- Reimplement Traversable interface
# If there is a problem with this i need a backtrace. As far as i can
# tell by gdb/valgrind/logic there is no error here. But missuse leads to
# the same error report casing the exclusion of interface Traversable.
