Messing with identity starts to get really scary and I'd rather not go
there - I'm sure there will be lots of edge cases which will be broken.  

I could see is making unicode(foo) do something different.  If you aliased 
unicode then you'd get str's behavior though but that might be perfectly 
acceptable.  It's definitely a solution I had not considered and it'd 
probably fix multiple issues.
