I wonder if this Dynamic Type finally allow heterogeneous data container to
be used in C#.
This is from the sample code
" static void Main(string[] args) {
Console.WriteLine("Loading helloworld.py...");
ScriptRuntime py = Python.CreateRuntime();
dynamic helloworld = py.UseFile("helloworld.py");
Console.WriteLine("helloworld.py loaded!");
for (int i = 0; i < 1000; i++)
{
Console.WriteLine(helloworld.welcome("Employee #{0}"), i);
}
Console.WriteLine();
}"
Now if helloworld actually returns a tuple or mixed typed array, can it
actually be used in the C# program?
