Agreed.  I will be following up with a more concrete idea (including 
p-code) to better describe what is currently in my brain.  (One half of 
which will be just as objectionable, the other half, with Alex 
Grönholm's input, far more reasonable.)

No, practically there is one.  If you are implementing a Python 3 
solution, a single value (original URI) is an instance of bytes, the 
rest are str.  If you are implementing a Python 2 solution, there's a 
single rule you need to remember: values derived from the URI 
(QUERY_STRING, PATH_INFO, etc.) are unicode, the rest are str.

Poloygot implementors are already accepting that they will need to 
include more in their headspace before writing a single line of code; 
knowing that "native string" differs between the two langauges is a 
fundamental concept nessicary for the act of writing polygot code.
