I see.

So to get this back to the point that was being made:

Phil said Ocaml allowed multiple _ in tuple assignments but
that Python did not, while I attempted to correct that assertion by
showing that it in fact did.

David and you were discussing a case involving function languages,
which Python is not, where the use of multiple _ (which now has
syntactical meaning, as opposed to being just an "ignore this" by
convention) is allowed.

Sounds to me like the two discussions are unrelated.
