Neal Norwitz	4886cc3	2006-08-21 17:06:07 +0000	[diff] [blame]	10	Release date: XX-XXX-200X
				11
				12	TO DO
				13	-----
				14
				15	- See PEP 3000.
				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	4886cc3	2006-08-21 17:06:07 +0000	[diff] [blame]	39	- Classic classes are a thing of the past. All classes are new style.
				40
				41	- Exceptions must derive from BaseException.
				42
				43	- Integer division always returns a float. The -Q option is no more.
				44	All the following are gone:
				45	* PyNumber_Divide and PyNumber_InPlaceDivide
				46	* __div__, __rdiv__, and __idiv__
				47	* nb_divide, nb_inplace_divide
				48	* operator.div, operator.idiv, operator.__div__, operator.__idiv__
				49	(Only __truediv__ and __floordiv__ remain, not sure how to handle them
				50	if we want to re-use __div__ and friends. If we do, it will make
				51	it harder to write code for both 2.x and 3.x.)
				52
				53	- 'as' and 'with' are keywords.
				54
				55	- Absolute import is the default behavior for 'import foo' etc.
				56
Neal Norwitz	378b2c9	2006-08-29 07:57:22 +0000	[diff] [blame^]	57	- Removed support for syntax:
				58	backticks (`x`), <>
				59
Neal Norwitz	4886cc3	2006-08-21 17:06:07 +0000	[diff] [blame]	60	- Removed these Python builtins:
				61	apply(), coerce(), input(), raw_input()
				62
Neal Norwitz	378b2c9	2006-08-29 07:57:22 +0000	[diff] [blame^]	63	- Removed these Python methods:
				64	{}.has_key
				65
Neal Norwitz	4886cc3	2006-08-21 17:06:07 +0000	[diff] [blame]	66	- Removed these Python slots:
				67	__coerce__, __div__, __idiv__, __rdiv__
				68
				69	- Removed these attributes from Python modules:
				70	* operator module: div, idiv, __div__, __idiv__
				71
Neal Norwitz	4886cc3	2006-08-21 17:06:07 +0000	[diff] [blame]	72	- Removed these C APIs:
Neal Norwitz	378b2c9	2006-08-29 07:57:22 +0000	[diff] [blame^]	73	PyNumber_Coerce(), PyNumber_CoerceEx()
Neal Norwitz	4886cc3	2006-08-21 17:06:07 +0000	[diff] [blame]	74
				75	- Removed these C slots/fields:
				76	nb_divide, nb_inplace_divide
				77
				78	- Removed these macros:
				79	staticforward, statichere, PyArg_GetInt, PyArg_NoArgs
				80
				81	- Removed these typedefs:
				82	intargfunc, intintargfunc, intobjargproc, intintobjargproc,
				83	getreadbufferproc, getwritebufferproc, getsegcountproc, getcharbufferproc
				84
				85	- Removed these opcodes:
Neal Norwitz	378b2c9	2006-08-29 07:57:22 +0000	[diff] [blame^]	86	BINARY_DIVIDE, INPLACE_DIVIDE, UNARY_CONVERT
				87
				88	- zip returns an iterator
				89
				90	- Additions:
				91	set literals
				92
