I defer to you.  Perhaps another approach will surface; in the meantime 
I'll start on the API change.

You suggested changing the name as a reminder of the semantics change.  
Are you interested in a structural change too?  My personal aesthetic 
for APIs is to return success/failure separately from output 
parameters.  So I propose something this:
    #define PyUnicode_VALUE(self, p, len)
which would return nonzero on success and zero on failure.  If it fails, 
p and len would be unchanged.

Let me know what you'd like and I'll make it happen.

Cheers,
