+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%. */
