Another issue is that a straight abc wouldn't be sufficient. What we would really want is to check for is: 1) the presence of a _fields tuple (an abc can do this) 2) to check that all of the attribute names specified in _fields are defined (ABCMeta doesn't do this) 3) and that the type is a Sequence (ABCMeta can do this). An tricked-out ABC extension might be worth it if it provided some non-trivial mixin capabilities for implementing homegrown named tuples (not created by the factory function), but I don't think we want to go there.
Instead of an ABC, why not a simple is_namedtuple() function?
