original_docstring: 
          Create a structured schema that will pass stream tuples into callables as ``tuple`` instances.
  
          If this instance represents a common schema then it will be returned
          without modification. Stream tuples with common schemas are
          always passed according to their definition.
  
          **Passing as tuple**
  
          When `named` evaluates to ``False`` then each stream tuple will
          be passed as a ``tuple``. For example with a structured schema
          of ``tuple<rstring id, float64 value>`` a value is passed as
          ``('TempSensor', 27.4)`` and access to the first attribute
          is ``t[0]`` and the second as ``t[1]`` where ``t`` represents
          the passed value..
  
          **Passing as named tuple**
  
          When `named` is ``True`` or a ``str`` then each stream tuple will
          be passed as a named tuple. For example with a structured schema
          of ``tuple<rstring id, float64 value>`` a value is passed as
          ``('TempSensor', 27.4)`` and access to the first attribute
          is ``t.id`` (or ``t[0]``) and the second as ``t.value`` (``t[1]``)
          where ``t`` represents the passed value.
  
          .. warning:: If an schema's attribute name is not a valid Python identifier or
              starts with an underscore then it will be renamed as positional name ``_n``.
              For example, with the schema ``tuple<int32 a, int32 def, int32 _id>`` the
              field names are ``a``, ``_1``, ``_2``.
  
  
          The value of `named` is used as the name of the named tuple
          class with ``StreamTuple`` used when `named` is ``True``.
  
          It is not guaranteed that the class of the namedtuple is the
          same for all callables processing tuples with the same
          structured schema, only that the tuple is a named tuple
          with the correct field names.
  
          Args:
              named: Pass stream tuples as a named tuple.
                  If not set then stream tuples are passed as
                  instances of ``tuple``.
  
          Returns:
              StreamSchema: Schema passing stream tuples as ``tuple`` if allowed.
