+Step 2: Check for calls to is_countable()
+==========================================
+
+
+PHP 7.3 introduces a native `is_countable() <https://secure.php.net/is_countable>`_
+function, which creates a name collision with the ``is_countable()`` function
+we've had in our :doc:`Inflector Helpers <../helpers/inflector_helper>`.
+
+If you've been using the helper function in question, you should now rename
+the calls to it to :php:func:`word_is_countable()`.
