This is looking more and more like a bug. I see from
http://stackoverflow.com/questions/799987/how-to-pass-a-lambda-expression-to-a-c-sharp-constructor-from-an-ironpython-scri
that it works for constructors (and have verified that it does), but I
can't figure out any way to make it work with a static method. Why the
difference?
If it is a bug, is there a workaround? How can I pass any Python
callable to a C# static method?
Any suggestions appreciated!
