				11
				12	TO DO
				13	-----
				14
Georg Brandl	66a796e	2006-12-19 20:50:34 +0000	[diff] [blame]	15	- See PEP 3000, 3100.
Neal Norwitz	4886cc3	2006-08-21 17:06:07 +0000	[diff] [blame]	16
				17	- Test merging certain changes from the 2.5 HEAD code.
				18
				19	- Weed really old/weird stuff from the library.
				20
				21	- Unify range() and xrange().
				22
				23	- Revamp the dict API: keys(), values(), items() return iterators, etc.
				24
				25	- Add the bytes type.
				26
				27	- Rework the standard I/O library to use bytes for binary files.
				28
				29	- Make strings all Unicode.
				30
				31	- Get rid of classic class implementation.
				32
				33	- Get rid of various compatibility-related flags (e.g. division flags).
				34

Neal Norwitz	4886cc3	2006-08-21 17:06:07 +0000	[diff] [blame]	36	Core and Builtins
				37	-----------------
				38
Neal Norwitz	c150536	2006-12-28 06:47:50 +0000	[diff] [blame^]	39	- Added function annotations per PEP 3107.
				40
Georg Brandl	66a796e	2006-12-19 20:50:34 +0000	[diff] [blame]	41	- Moved intern() to sys.intern().
				42
				43	- exec is now a function.
				44
				45	- Renamed nb_nonzero to nb_bool and __nonzero__ to __bool__.
Jack Diederich	4dafcc4	2006-11-28 19:15:13 +0000	[diff] [blame]	46
Neal Norwitz	4886cc3	2006-08-21 17:06:07 +0000	[diff] [blame]	47	- Classic classes are a thing of the past. All classes are new style.
				48
				49	- Exceptions must derive from BaseException.
				50
				51	- Integer division always returns a float. The -Q option is no more.
				52	All the following are gone:
				53	* PyNumber_Divide and PyNumber_InPlaceDivide
				54	* __div__, __rdiv__, and __idiv__
				55	* nb_divide, nb_inplace_divide
				56	* operator.div, operator.idiv, operator.__div__, operator.__idiv__
				57	(Only __truediv__ and __floordiv__ remain, not sure how to handle them
				58	if we want to re-use __div__ and friends. If we do, it will make
				59	it harder to write code for both 2.x and 3.x.)
				60
				61	- 'as' and 'with' are keywords.
				62
				63	- Absolute import is the default behavior for 'import foo' etc.
				64
Neal Norwitz	378b2c9	2006-08-29 07:57:22 +0000	[diff] [blame]	65	- Removed support for syntax:
				66	backticks (`x`), <>
				67
Neal Norwitz	4886cc3	2006-08-21 17:06:07 +0000	[diff] [blame]	68	- Removed these Python builtins:
				69	apply(), coerce(), input(), raw_input()
				70
Neal Norwitz	378b2c9	2006-08-29 07:57:22 +0000	[diff] [blame]	71	- Removed these Python methods:
				72	{}.has_key
				73
Neal Norwitz	4886cc3	2006-08-21 17:06:07 +0000	[diff] [blame]	74	- Removed these Python slots:
				75	__coerce__, __div__, __idiv__, __rdiv__
				76
				77	- Removed these attributes from Python modules:
				78	* operator module: div, idiv, __div__, __idiv__
				79
Neal Norwitz	4886cc3	2006-08-21 17:06:07 +0000	[diff] [blame]	80	- Removed these C APIs:
Neal Norwitz	378b2c9	2006-08-29 07:57:22 +0000	[diff] [blame]	81	PyNumber_Coerce(), PyNumber_CoerceEx()
Neal Norwitz	4886cc3	2006-08-21 17:06:07 +0000	[diff] [blame]	82
				83	- Removed these C slots/fields:
				84	nb_divide, nb_inplace_divide
				85
				86	- Removed these macros:
				87	staticforward, statichere, PyArg_GetInt, PyArg_NoArgs
				88
				89	- Removed these typedefs:
				90	intargfunc, intintargfunc, intobjargproc, intintobjargproc,
				91	getreadbufferproc, getwritebufferproc, getsegcountproc, getcharbufferproc
				92
				93	- Removed these opcodes:
Neal Norwitz	378b2c9	2006-08-29 07:57:22 +0000	[diff] [blame]	94	BINARY_DIVIDE, INPLACE_DIVIDE, UNARY_CONVERT
				95
				96	- zip returns an iterator
				97
				98	- Additions:
Georg Brandl	66a796e	2006-12-19 20:50:34 +0000	[diff] [blame]	99	set literals, ellipsis literal
