I've noticed that the patch is outdated already, so here is the rebased
version. I also removed the last part with the extra tests since it
was something
internal and merged the debug message into the implementation part. Ashutosh,
please let me know if you're not happy with these modifications.

Other than that I haven't changed anything yet, but hope this will come soon.
And this version is more to keep it updated for those people who may be
interested.
