[IronPython] IP 2: Execute multiple expression in different scopes

[Christian Schmidt]

Hi Curt,

thanks for your answer. It's an interesting idea, to hand over the items 
as function arguments. I was trying to add them to the ScriptScope.

But I'm still stuck with calling the function:

ScriptScope scope =
   ScriptRuntime.Create().GetEngine("py").CreateScope();
scope.Execute("from math import *");
scope.Execute(@"
def process(a, b, c):
   return [a+b, sqrt(b*c)]
");
object process = scope.GetVariable("process");
foreach(object[] row in data)
   object[] result = process(row); // ??

How do I call the function?

I have some further question regarding this approach:

1. Will the function be interpreted on each call or is it compiled?
2. Is the number of arguments limited? I could have up to 200 arguments.

Meanwhile I've tried the CustomSymbolDictionary way, but couldn't find 
any helpful tutorial.

Thanks for your time,
Christian
