Excellent! Thanks much for this.

I've taken a look at the updated text, and have a question about evaluating arbitrary user text. I'm allowing the user to evaluate an arbitrary expression OR a sequence of statements. If I use:

 source = engine.CreateScriptSourceFromString(code, SourceCodeKind.Statements);
 object result = source.Execute(scope);

then it works for statements (with a null result). If I use:

 source = engine.CreateScriptSourceFromString(code, SourceCodeKind.InteractiveCode);
 object result = source.Execute(scope);

then that works fine with REPL expressions. As there isn't a Kind for either, would there be issues if I do:

try {
   source = engine.CreateScriptSourceFromString(code, SourceCodeKind.Statements);
} catch (Exception e1) {
   try {
      source = engine.CreateScriptSourceFromString(code, SourceCodeKind.InteractiveCode);
   } catch (Exception e2) {
      // report error
   }
}

or is there a better way?

Thanks!
