I think that another important difference between str() and repr() is 
that repr() is often used as an embedded string in other objects' 
representations; but str() usually is not.  Thus, the string returned by 
repr() should not span multiple lines, and it should be easy to match up 
its beginning with its end.  str() doesn't have these restrictions.

So actually, it can sometimes be convenient to use both for debugging 
purposes, with repr() for a short string, suitable for embedding, and 
str() for a more verbose, multiline, formatted string.

(Another -1 for combining them.)
