I'm not a big fan of the names, but as long as the functionality exists, 
people can easily alias them as necessary.

I've not actually looked at the patch, but as long as it does what it 
says it does, it looks good.

My only question, does it makes sense to backport this to trunk so we 
get this in 2.7?  I personally would like to see it there, and would 
even be ok with a limitation that it only exists as part of longs.  If 
someone has the time to backport it; cool.  If not, I understand, and 
could live with it only being in 3.x .

Thank you for taking the time and making the effort in getting this into 
a recent Python :)
