Some time back contributors to this forum were invited to suggest which Python3k and Python 2.6 functions were most important to implement in the next IronPython.
I downloaded Python 2.6 and Python3.0RC2 today and started hacking at making adodbapi work in Python 3. (Now that it works in Iron, py3k seems like the next logical thing.) Conversion to Python2.6 is the first baby step. Roger Upole has already done some of the work, so I picked up his branch off CVS.
I quickly discovered that the first thing I need for each module is to add:
from __future__ import print_function
from __future__ import unicode_literals
This makes IronPython immediatly error out, of course.
The unicode_literals would be a simple "pass" statement for IronPython, which already defaults that way.
The convertion of "print" from a statement to a function affects every Python program down to "Hello, World". IMHO it would be the most important thing to implement.
