-Type PyStringObject represents a character string.  An extra zero byte is
-reserved at the end to ensure it is zero-terminated, but a size is
-present so strings with null bytes in them can be represented.  This
-is an immutable object type.
-
-There are functions to create new string objects, to test
-an object for string-ness, and to get the
-string value.  The latter function returns a null pointer
-if the object is not of the proper type.
-There is a variant that takes an explicit size as well as a
-variant that assumes a zero-terminated string.  Note that none of the
-functions should be applied to nil objects.

-/* Caching the hash (ob_shash) saves recalculation of a string's hash value.
-   Interning strings (ob_sstate) tries to ensure that only one string
-   object with a given value exists, so equality tests can be one pointer
-   comparison.  This is generally restricted to strings that "look like"
-   Python identifiers, although the intern() builtin can be used to force
-   interning of any string.
-   Together, these sped the interpreter by up to 20%. */
