[IronPython] Hosting IronPython 2.X in .NET app

Does Kamaelia use the new syntax as supported via PEP-342 (http://www.python.org/dev/peps/pep-0342/).  That’s the particular piece that we don’t support and is new to 2.5 – we do support generators when you use yield as a statement instead of as an expression (in other words, we don’t support the send method on the generator – only next).  It’s hard to tell as 1.5.1 was released shortly after Python 2.5 and I don’t see any statements about which version of Python is required.

Looking at all the various things it supports I would be shocked if there wasn’t some use of the C-based extension API (which would prevent, at least some portions, from working).

Not to worry :)
However the question stands, will Python support closures (or does it
already via lambda expressions?)

Depends on your interpretation of what a closure is.  One interpretation is that w ith closures you can, for example, have a series of lambda expressions, evaluate up to a certain point, add a marker, store it, and then continue where you left off at a later date.

As per our conversation in IM, this would certainly be one way to move towards a stackless and thread-free Python diet. ;-)

Also, since we're on the subject, one *true test* of Python language interoperability would be to get Kamaelia ( http://kamaelia.org ) to work properly via IronPython.

Kamaelia list (Cc'd): Has anyone attempted to get Kamaelia working with IronPython?  If I am understanding things correctly, until support for generators are implemented then this would not be possible.  Is this understanding correct?

To the IronPython team: Having the ability to run Kamaelia (a brainchild of Michael Sparks of BBC Research) via IronPython would be an absolute dream come true.  *AMAZING* potential existing bridging together Kamaelia and .NET, in my own opinion.
