actually that one  is not against - it certainly removes a _very_ common 
mistake - namely: "some string: %s" % tuple - and makes it very clear 
that you should either write: "some string: %s"(tuple) or "some string: 
%s"(*tuple) - and neither would give breakage - whereas current breaks 
in case of len(tuple) is 1.

not that i'm for this change, mind you ;-)
