Summary: convert library to use inplace ops

Initial Comment:
The Python library contains a large number of lines 
which could be converted to use inplace operators 
("+=" and friends).  That would make the library 
modules marginally smaller and faster.

The attached program identifies these cases and prints 
out a list.  It has found 647 instances in 91 files of 
the 2.2a2 library.

There are so many of these that I recommend that a 
tool be made to automatically convert these things.  
Failing that, perhaps at least the most frequently-
used modules could be manually converted.  (For 
example, sre and fnmatch [used by glob] contain a few 
of these.)

If there's any interest in a conversion tool, I could 
take a shot at doing it.  (It could be done fairly 
easily by adapting the attached program.)

thanks,
