-CPython version 2.2 compatibility of PyPy
-
-History
-  Seo Sanghyeon, 2005-04-06 (r10349)
-
-First, you should use CPython version 2.3 or greater to run PyPy.
-Running PyPy on top of 2.2 is definitely NOT supported.
-
-That said, there are some supports in the code to run PyPy
-on top of 2.2, most notably "from __future__ import generators".
-This document lists some of known problems.
-
-* opcode.py
-opcode module is new in 2.3, and is used in the interpreter core.
-Just copying this file from 2.3 should work. Without this, PyPy
-won't even start.
-
-* boolean
-In 2.2, bool is a builtin_function_or_method, not a type. This breaks
-anything boolean related in the annotator.
-
-* func_with_new_name
-pypy.tool.hack has a code to rename already defined function, which
-is disabled for 2.2. You lose descriptive names like binop_xxx_impl,
-and some gateway tests checking function name will fail.
-
-* operator.is_
-In 2.2, operator module doesn't include "is_(a, b)", which should be
-equivalent to "a is b". This causes some problem in the flow objspace.
-
-* issubclass
-2.2 doesn't allow tuple as the second argument to issubclass. This
-affects the annotator.
-
-* extended slice
-2.2 can't do extended slice -- the optional third argument in slicing
-syntax. This affects the trace objspace.
-
-* C module
-Anything using new-in-2.3 features of borrowed C modules won't work.
-For example, socket.settimeout.
-
-* C API
-All genc tests will fail due to difference between Python C headers.
-
-* universal newline
-Universal newline support is new in 2.3. This lets tests for builtin
-module testing this feature to fail.
-
-* int long unification
-In 2.2, int() will raise OverflowError if argument is too large to
-convert to int. In 2.3, this silently returns long. Tests explicitly
-testing this does fail.
-
-* generators
-Files using generators have needed __future__ import at the top
-of the file. This should cause no problem.
-
-* exec without newline
-It is a SyntaxError to exec string without trailing newline in 2.2.
-This is CPython bug #501622. All known instances of this is worked
-around.
-
-* misc features
-"string in string" doesn't work in 2.2. dict.pop and dict.fromkeys
-is new in 2.3. These have caused problems in the past.
