+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 keyword-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
+    ``_helpers.positional_parameters_enforcement``, which may be set to
+    ``POSITIONAL_EXCEPTION``, ``POSITIONAL_WARNING`` or
+    ``POSITIONAL_IGNORE`` to raise an exception, log a warning, or do
+    nothing, respectively, if a declaration is violated.
