That might work, but I don't want to use it that way. Developing introductory educational materials, and I don't want to blow any young minds... just yet :) > Oh, and please open an issue on Codeplex with a minimal reproduction, > if you can. Will do! Can you think of *any* workaround on the C# side? Nothing I have tried will allow me to get a Python-based function (lambda, PythonFunction, builtin) out of an IList as a Func. -Doug > - Jeff _______________________________________________ Ironpython-users mailing list Ironpython-users@python.org http://mail.python.org/mailman/listinfo/ironpython-users
