+Native tuple operations
+=======================
+
+These ``tuple`` operations have fast, optimized implementations. Other
+tuple operations use generic implementations that are often slower.
+
+Unless mentioned otherwise, these operations apply to both fixed-length
+tuples and variable-length tuples.
+
+Construction
+------------
+
+* ``item0, ..., itemN`` (construct a tuple)
+* ``tuple(lst: list)`` (construct a variable-length tuple)
+* ``tuple(lst: Iterable)`` (construct a variable-length tuple)
+
+Operators
+---------
+
+* ``tup[n]`` (integer index)
+* ``tup[n:m]``, ``tup[n:]``, ``tup[:m]`` (slicing)
+
+Statements
+----------
+
+* ``item0, ..., itemN = tup`` (for fixed-length tuples)
+
+Functions
+---------
+
+* ``len(tup: tuple)``
