 Fix the output of :mod:`marshal` for compiled code, and so the content of
-``.pyc`` files, depending on what was imported or compiled before in the
-process.  A :class:`frozenset` constant (or, in the :term:`free-threaded
-build`, a :class:`slice` constant) used by several functions of a module was
-copied for each of them when one of its strings was equal to a string which
-was already interned.  The compiler now replaces the strings of the
-constants by the interned ones before the code objects are created, while
-equal constants are still one object.  Which strings are interned does not
-change, except for the strings of :class:`slice` constants made only of ASCII
-letters, digits and underscores, which are now interned in the default build
-like those of other constants.
