Comment (by jrf):

 @thrijith Thank you for your contributions to this! I'll try to review the
 patches later this week.

 As a general - but important - side-note (without having reviewed the
 patches): `is_countable()` should only be added when needed, not blindly
 to every `count()`.
 If an array is expected somewhere and the variable being tested is not a
 parameter being passed in or the output of a `apply_filters()` call either
 in the function in question or in a function from which the output is
 being used, `is_countable()` should not be added as it should not be
 needed and adding it may hide bugs which should be solved instead.
