first, thanks for your ongoing work. A couple of quick feedbacks, before 
I leave for a few days of vacations:

1- While waiting for your copyright assignment procedure to complete, I 
would suggest practicing with 'svn diff' and the standard way of 
submitting patches (just have a look to this mailing list and 
gcc-patches@ to learn how to properly submit patches for review).

2- If I remember correctly, tuple can certainly take advantage of 
decltype, which luckily Doug already implemented. While you are updating 
tuple, I would suggest looking into that too, if possible...

Thanks,
Paolo.
