Some quick notes about the coming plans by the “other” Python implementations from today’s Python Language Summit at PyCon 2010:

• IronPython:
  • plan is to do Python 2.7 first, focus for this year
  • python 3.2 for the end of next year hopefully
  • other work on IDE stuff
• Pynie (i.e. Parrot) – Allison Randall:
  • about 4 major features away from pure Python syntax (did dicts last night)
  • targetting py3k repo and test suite: should be on track for python 3.2
• Jython:
  • plan to target 2.6 (b/c 2to3 depends on 2.6)
  • temporarily skip 2.7 and target 3.x (probably 3.2)
  • then if 3.x adoption isn’t fully there, then go back and add Python 2.7
  • will require JDK 2.7 for Python 3 support (b/c of new support for dynamic languages)
• PyPy (Holger):
  • plan is Benjamin will port to Python 2.7 in the summer
  • only have slight deviations from CPython: idea is to merge back with CPython so don’t have deviations. Typcically 1 or 2 line changes in ~25 modules.
