In general, I don't like such caveats. Either something is in the
language or it is not.

You don't have to use all language features (I certainly don't), but if
somebody takes advantage of them, you shouldn't consider it bad style.

    if prev_node is not node in excluded:
         ...

take your complaints to whoever accepted the syntax in the language.
