Exceptions propogated by 'ask' include stack trace in message

[OlduwanSteve]

If an inbox throws an exception then it seems like the ask ing process gets an exception where the original stack trace is appended to the message. In some scenarios it might be 'helpful' (relatively) to surface the message without exposing the stack trace but currently this would be hard.

Could the stack trace perhaps be included as exception data instead?

@OlduwanSteve I'm a little unclear of what you're asking to be honest. Are you saying there isn't stack trace info and you want it? Or are you saying you don't want stack trace data? Grab me on Skype tomorrow and we can discuss it.

Here's some sample code:

    class Program
    {
        static ProcessId a;

        static void Main(string[] args)
        {
            ProcessConfig.initialise();
            a = spawn<int>("a", GetData);

            try
            {
                var dt = ask<int>(a, 0);
            }
            catch (ProcessException e)
            {
                Console.WriteLine(e.InnerException.Message);
            }
        }

        private static void GetData(int obj)
        {
            throw new Exception("fail");
        }
    }

This program outputs:

System.Exception: fail
   at ep_datatable_bug.Program.GetData(Int32 obj) in c:\Users\Steve\Documents\Visual Studio 2017\Projects\ep-datatable-bug\ep-datatable-bug\Program.cs:line 30
   at Echo.Process.<>c__DisplayClass141_0`1.<spawn>b__1(Unit state, T msg)
   at Echo.Actor`2.ProcessAsk(ActorRequest request)

But I would expect it to output:

fail
