This is a collection of no-op statements that are syntactically valid
only since Python *X*.\ *Y*, for most *X*.\ *Y* ≥ 2.2.

For example:

.. code:: python

0_0 # Python >= 3.6 is required

The idea is to put such a statement near the top of your file.
If a user inadvertently ran the code against an older version,
they would get a fairly helpful error message:

.. code:: console

$ python3.5 since-3.6.py
File "since-3.6.py", line 1
0_0 # Python >= 3.6 is required
^
SyntaxError: invalid syntax
