PEP 3135 -- New Super

http://www.python.org/dev/peps/pep-3135/

PEP 409 -- Suppressing exception context

http://www.python.org/dev/peps/pep-0409/.

Requires PEP 3134 (#3).

change xrange to be range

As per 3.0 xrange is renamed to range and range (list) is gone.
As per 3.0 range must conform to int/long unification and return longs.

Reference: https://docs.python.org/3.4/library/stdtypes.html#ranges

PEP 3154 -- Pickle protocol version 4

http://www.python.org/dev/peps/pep-3154/

PEP 383 -- Non-decodable Bytes in System Character Interfaces

http://www.python.org/dev/peps/pep-0383/

May already be implemented.

PEP 3100 -- Miscellaneous Python 3.0 Plans

http://www.python.org/dev/peps/pep-3100/

A lot of stuff is covered in here; there really should have been multiple PEPs. More issues should be created from this.

PEP 3106 -- Revamping dict.keys(), .values() and .items()

http://www.python.org/dev/peps/pep-3106/

is it completely in managed code?

I think the title explains it all, also a question of stability
Many thanks

PEP 3110 -- Catching Exceptions in Python 3000

http://www.python.org/dev/peps/pep-3110/

PEP 380 -- Syntax for Delegating to a Subgenerator

http://www.python.org/dev/peps/pep-0380/

in Python3, the module __builtin__ has been renamed to builtins (out of stackoverflow)
http://docs.python.org/3.4/reference/executionmodel.html#naming-and-binding
http://docs.python.org/2.7/reference/executionmodel.html#naming-and-binding
There is nothing in PEPs or release notes I can find about it. Documentation says, it is an cpython implementation detail, but it must be an important one since StdLib has 41 hits on import builtins

PEP 3138 -- String representation in Python 3000

What’s New In Python 3.4

errors from IronPythonTestConsole should include python exception details

PEP 237 -- int/long Unification

Python 3 gets rid of the distinction between int and long, with int now behaving as long. One way would be to switch everything to BigInteger, but it might be more efficient to try and use Int32 as much as possible behind the scenes, and switch to BigInteger if we have to while keeping the visible type int at all times.

Probably worth doing some benchmarks to see if it's worthwhile first.

PEP 3148 -- futures - execute computations asynchronously

http://www.python.org/dev/peps/pep-3148/

Clean up setting prefix/exec_prefix during startup

prefix (Lib location) and exec_prefix (Include location, not used in IronPython) get set multiple times in multiple places, using inconsistent locations, during interpreter startup. Arguably the DLLs shouldn't even try to set the prefix and instead rely on getting it from the host, which will know where it's stdlib is stored.

IronPython DataGridView: Get Value from One Key Press But Without Pressing 'Enter' and Move to the Next Cell

I've been struggling with the difficulty for a few days. I've read on http://www.ironpython.info/ and book 'IronPython In Action' by Michael and Christian, and DataGridView class on https://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview(v=vs.110).aspx, but I'm still lack of some knowledge and skills.
My question is how to get value from one key press but without pressing 'Enter' and Move to the next cell, which means when I press one number on keyboard but without pressing 'Enter', the number is passed into the first cell such as 3, and then the next cell is active. The sequence is meander, like row 1 col 1 -> row 1 col 2 -> ... -> row 1 col 12 -> row 2 col 12 -> row 2 col 11. I tried many events of DataGridView such as 'CellEnter' and 'KeyPress', but failed.
If you could give some hints about it, I'll appreciate it very much.
The following is my code up to now:

Sorry for the mysterious error messages. I'm on a localized Windows box :(
Any idea how can I get it to work? I've installed VS2013 Community Edition and I can build just IronPython 2.x fine.

Thanks in advance!
