Hello,
The PyUnicode_KIND_SIZE macro is defined as follows. Its name looks
rather mysterious or misleading to me. Could we rename it to something
else?
(also, is it useful? PEP 393 has added a flurry of new macros to
unicodeobject.h and it's getting hard to know which ones are genuinely
useful, or well-performing)
/* Compute (index * char_size) where char_size is 2 ** (kind - 1).
The index is a character index, the result is a size in bytes.
See also PyUnicode_CHARACTER_SIZE(). */
#define PyUnicode_KIND_SIZE(kind, index) \
((Py_ssize_t) ((index) << ((kind) - 1)))
Regards
Antoine.
