"List<IronPython.NewTypes.System.Object_1$2> isn't even type-safe for Python classes because IronPython maintains a cache of generated types and will reuse a type it has previously generated for any new class you define that's compatible with a previously-defined class."
This has always been a lingering thought in the back of my head - I've been wondering how long it'd be until it came up. From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Curt Hagenlocher Sent: Friday, May 02, 2008 10:17 PM To: Discussion of IronPython Subject: Re: [IronPython] List<Python Class> Well in the example I gave, the type of class foo would genrally be something like IronPython.NewTypes.System.Object_1$2. There's not going to be any "native" CLR code to which you can pass a List<IronPython.NewTypes.System.Object_1$2>, and if you're passing the data to other Python code, you may as well do it as a Python list or tuple. It's the "dynamic" thing to do :). List<IronPython.NewTypes.System.Object_1$2> isn't even type-safe for Python classes because IronPython maintains a cache of generated types and will reuse a type it has previously generated for any new class you define that's compatible with a previously-defined class.

Is there a caveat to the dynamic typing that I'm missing?
