+def positional(max_positional_args):
+  """A decorator to declare that only the first N arguments my be positional.
+
+  This decorator makes it easy to support Python 3 style key-word only
+  parameters. For example, in Python 3 it is possible to write:
+
+    def fn(pos1, *, kwonly1=None, kwonly1=None):
+      ...
+
+  All named parameters after * must be a keyword:
+
+    fn(10, 'kw1', 'kw2')  # Raises exception.
+    fn(10, kwonly1='kw1')  # Ok.
+
+  Example:
+    To define a function like above, do:
+
+      @positional(1)
+      def fn(pos1, kwonly1=None, kwonly2=None):
+        ...
+
+    If no default value is provided to a keyword argument, it becomes a required
+    keyword argument:
+
+      @positional(0)
+      def fn(required_kw):
+        ...
+
+    This must be called with the keyword parameter:
+
+      fn()  # Raises exception.
+      fn(10)  # Raises exception.
+      fn(required_kw=10)  # Ok.
+
+    When defining instance or class methods always remember to account for
+    'self' and 'cls':
+
+      class MyClass(object):
+
+        @positional(2)
+        def my_method(self, pos1, kwonly1=None):
+          ...
+
+        @classmethod
+        @positional(2)
+        def my_method(cls, pos1, kwonly1=None):
+          ...
+
+  The positional decorator behavior is controlled by the
+  --positional_parameters_enforcement flag. The flag may be set to 'EXCEPTION',
+  'WARNING' or 'IGNORE' to raise an exception, log a warning, or do nothing,
+  respectively, if a declaration is violated.
+
+  Args:
+    max_positional_arguments: Maximum number of positional arguments. All
+      parameters after the this index must be keyword only.

+    being used as positional parameters.
+
+  Raises:
+    TypeError if a key-word only argument is provided as a positional parameter,
+    but only if the --positional_parameters_enforcement flag is set to
+    'EXCEPTION'.
