+#
+# Add C++ overloads for _Py_CAST_impl() to handle 0/NULL.  This will allow
+# C++ extensions that pass 0 or NULL to macros using _Py_CAST() to
+# continue to compile.  Without this, you get an error like:
+#
+#     invalid ‘static_cast’ from type ‘int’ to type ‘_object*’
+#
+# The modern way to use a NULL value in C++ is to use nullptr.  However,
+# we want to not break extensions that do things the old way.
