Arghhh... we cannot use the plain unicode to represent ObjC strings 
because you may want to directly access the ObjC string, maybe because 
it is a mutable string or because you want to use one of the gazillion 
methods that have no direct python equivalent. We decided to subclass 
the unicode type to make it easier to use ObjC strings in python: 
Passing them to extension modules expecting strings or unicode objects 
"just works".  SRE doesn't work because it tests types using '==' 
instead of 'isinstance'. IMHO this is a bug in SRE.
