// Statistics on Python performance.
//
// API:
//
// - _Py_INCREF_STAT_INC() and _Py_DECREF_STAT_INC() used by Py_INCREF()
//   and Py_DECREF().
// - _Py_stats variable
//
// Functions of the sys module:
//
// - sys._stats_on()
// - sys._stats_off()
// - sys._stats_clear()
// - sys._stats_dump()
//
// Python must be built with ./configure --enable-pystats to define the
// Py_STATS macro.
//
// Define _PY_INTERPRETER macro to increment interpreter_increfs and
// interpreter_decrefs. Otherwise, increment increfs and decrefs.
//
// The number of incref operations counted by `incref` and
// `interpreter_incref` is the number of increment operations, which is
// not equal to the total of all reference counts. A single increment
// operation may increase the reference count of an object by more than
// one. For example, see `_Py_RefcntAdd`.
