Idiomatic code validator?

Strictly speaking, there cannot be a mechanical PEP 8 validator, as any 
mechanical checker violates the admonitions of the beginning sections 
'Introductions' and 'A Foolish Consistency is the Hobgoblin of Little 
Minds'.  For this reason, the core developers request the author of the 
checker formerly known as 'pep8' to change its name, which he did.

What would such a thing do?  Flag supposedly non-idiomatic code?  Or 
mark code recognized as 'idiomatic', with no implication either way 
about other code?

Do they all agree on 'idiomatic'?  I am sure that the long-time frequent 
contributors on python list do not.
