While I understand the rationale against __version__, it strikes me as a 
better description of what it is, and easier on the brain than 
__cache_token__.  Maybe there is something even better, such as 
__seqnum__.  This is literally what the attribute
is, a sequence/revision number, as with the Python repository, without 
the connotations of 'version', as in 'Python version'.  Each commit to 
CPython changes the repository state without changing the 'version'. A 
dict.update may run thru 1000s of sequence numbers, but only the final 
result is a 'version' from the programmers point of view.
