Another suggestion: rather than adding the clumsy sub() method,
how about overloading a unary prefix operator on strings?  For
example the unary minus sign: say

   print -"my name is ${name}"

instead of

   print "my name is ${name}".sub()

Note that unlike PEP 215, this is not a syntax change.  It's just
operator overloading.  I think it can already be implemented
in Python 2.2 using a string subclass.  In fact perhaps PEP 215
can be implemented the same way, using "-" as the prefix instead of "$".
