README
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
.. vim:ft=rst ts=3 sts=3 sw=3 et
