* Since PHP 7.0, functions inspecting arguments, like func_get_args() and
  debug_backtrace() no longer report the original value as passed to a
  parameter, but will instead provide the current value.
  * The locations phpcs found don't appear to be impacted though. Supressing
    the warning.
* PHP has reserved all method names with a double underscore prefix.
