I don't think anybody was proposing any such tracking, simply a shorthand for this:
array_map(strval(...), array_keys($array));
In other words, take the keys of any array, which might be a mixture of integers and strings, and
convert them all to strings, regardless of how they were originally specified. The result being an
array where the values can all be safely passed to a function expecting strings, with strict_types=1
in force.
