Many newbie code I have seen avoids it by string concatenation:

greeting = 'Hello, my name is ' + name + ' and I am ' + str(age) + ' old.'

That's some kind of indirect complaint.  :-)

And even if nobody has problems with the limitations of ``%`` string 
formatting why shouldn't they add a more flexible and powerful way!?  
Python 3.0 is not a bug fix release.
