Is there a notion of "Warning" in context of execution? My understanding is that during execution you either get a single error, or you get the resulting value (or void/null if the script does not eval to a return value). Any print() messages are routed to the stdout stream which you can also intercept via the script engine's IO property. Perhaps that kind of trace output is what you are looking for?

It's not about the errors, but about the warnings. We run IronPython embedded (hosted) in our application, and want to capture the warnings to display them in a different window.
