When Microsoft handed IronPython over to the open source community I was actually quite pleased, I thought we'd see faster progress, more incremental releases, regular checkins, etc. Ideally, a fork/pull style setup line github projects.
However, the latest checkin is nearly three month old and the last release was an alpha. I would have expected at least daily/weekly commits. Unless the new team have taken a faux open source / open contribution style -- ala ASP.NET MVC, with a separate repository behind closed doors -- then I can only conclude that the project is dying.
As someone learning bits of Python in small bits (mainly daily exercises) should I jump from it now and go directly to CPython? Before I pick up bad traits from a semi-standard implementation?
Yes, I've seen the blogs from mid/late last year IronPython is not dead. But reality tells a different story when you look at key metrics such as checkins and releases.
